[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0025] First, a brief description of the relevant content involved in this invention will be given.

[0026] Rare earth elements have a wide range of applications in metallurgy, glass, ceramics, chemical industry, atomic energy, magnetic materials, luminescent and laser materials, agriculture and medicine, and have particularly broad application prospects in the fields of renewable energy and high-performance materials.

[0027] Compared with traditional rare earth mineral deposits, ion adsorption type rare earth deposits have a complete distribution of rare earth elements, and the extraction process is simple with low radioactivity. In particular, they are the main source of medium and heavy rare earth elements and are rare high-quality rare earth resources.

[0028] Relevant studies mainly focus on the regional distribution of ion adsorption type rare earth deposits, the age of ore-forming rock bodies, and the secondary enrichment mechanism of rare earth elements. Most of these studies are single-factor studies, with few systematic results accumulated. There has been no systematic evaluation of the control of different factors on rare earth mineralization. As a result, the reliability of the mineralization mechanism is low, which leads to low accuracy in calculating mineralization probability and poor accuracy in target area determination in existing prospecting models.

[0029] To address the above problems, this invention provides an ion adsorption-based method and apparatus for identifying rare earth minerals.

[0030] The following is combined with Figures 1-4 The present invention describes the ion adsorption-based rare earth mineral identification method and apparatus.

[0031] Figure 1 This is a schematic flowchart of the ion adsorption-based rare earth mineral identification method provided by the present invention. Figure 1 As shown, this ion adsorption-based rare earth mineral identification method includes: Step 101: Based on the pre-constructed mineralization conditions of ion-adsorption type rare earth minerals, identify whether the target area is a potential mineralization target area of ​​the ion-adsorption type rare earth minerals.

[0032] Specifically, the target area refers to the area that needs to be identified as an ion-adsorption type rare earth mineral, i.e., the area to be identified; the mineralization conditions of ion-adsorption type rare earth minerals refer to the conditions for the formation of ion-adsorption type rare earth minerals, including at least one of the following in China: geological conditions, environmental conditions, climatic conditions, and rock mass conditions.

[0033] In practical applications, one can first obtain the pre-constructed mineralization conditions of ion-adsorption type rare earth minerals, and then, based on the mineralization conditions of ion-adsorption type rare earth minerals, collect the regional characteristics corresponding to the target area, such as geological characteristics, environmental characteristics, climate characteristics, and rock mass characteristics.

[0034] Furthermore, the regional features corresponding to the collected target area are compared with the mineralization conditions of ion-adsorption type rare earth minerals to determine whether the regional features corresponding to the target area meet the mineralization conditions of ion-adsorption type rare earth minerals. If they do, the target area is identified as a potential mineralization target area for ion-adsorption type rare earth minerals; if they do not, the target area is identified as not a potential mineralization target area for ion-adsorption type rare earth minerals.

[0035] It should be noted that before identifying ion-adsorption type rare earth minerals, it is necessary to construct the mineralization conditions of ion-adsorption type rare earth minerals. After that, the pre-constructed mineralization conditions of ion-adsorption type rare earth minerals can be used to identify ion-adsorption type rare earth minerals in any region.

[0036] See Figure 2 , Figure 2 This is a schematic flowchart illustrating the process of constructing mineralization conditions according to the present invention. The process of constructing the mineralization conditions for the ion-adsorption type rare earth ore includes: Step 201: Obtain a sample set of known ion adsorption type rare earth minerals, the sample set including samples for diagenetic age detection and samples for elemental information determination; Step 202: Based on the diagenetic age test sample and the elemental information determination sample, perform feature detection to obtain the ore-forming rock mass characteristics of the known ion adsorption type rare earth ore; Step 203: Based on the rare earth element enrichment of the known ion adsorption type rare earth ore, determine the main controlling factors of mineralization of the known ion adsorption type rare earth ore from multiple mineralization influencing factors; Step 204: Based on the characteristics of the ore-forming rock mass and the main controlling factors of ore formation, construct the ore-forming conditions of the ion adsorption type rare earth ore.

[0037] Specifically, known ion-adsorption type rare earth minerals refer to ion-adsorption type rare earth minerals that have been identified through actual exploration. The number of known ion-adsorption type rare earth minerals can be one. In order to improve the mineralization conditions of ion-adsorption type rare earth minerals, the commonalities of ion-adsorption type rare earth minerals can be covered, avoiding the uniqueness of a single known ion-adsorption type rare earth mineral in certain aspects, thereby improving the accuracy of the mineralization conditions of ion-adsorption type rare earth minerals. The number of known ion-adsorption type rare earth minerals can be multiple.

[0038] Specifically, diagenetic age testing samples refer to samples used to determine the age of diagenesis, while elemental information determination samples refer to samples used to detect information related to the elements contained in known ion-adsorption type rare earth minerals. Ore-forming rock mass characteristics refer to the relevant features of the diagenetic rock mass, such as its diagenetic age and elemental information, where elemental information refers to information related to the elements contained within the rock mass.

[0039] Specifically, rare earth element enrichment refers to the phenomenon of rare earth elements accumulating in the environmental medium during migration due to physical, chemical, or biological processes; rare earth element enrichment status refers to the degree of rare earth element enrichment in a known ion-adsorption type rare earth ore.

[0040] Specifically, mineralization influencing factors refer to factors that affect the formation of mineral deposits, such as bedrock properties, topography, weathering and leaching, and climate and vegetation factors. Among these, weathering and leaching include weathering and alteration as well as leaching, and climate and vegetation factors include climate factors and vegetation factors. Mineralization controlling factors refer to the main factors that affect the formation of mineral deposits.

[0041] In practical applications, samples for rock age determination and elemental information determination can be collected from at least one known ion-adsorption type rare earth ore to obtain a sample set. Feature detection is then performed on the collected samples for rock age determination and elemental information determination to obtain the ore-forming rock mass characteristics of the known ion-adsorption type rare earth ore.

[0042] In addition, the rare earth element enrichment of known ion-adsorption type rare earth minerals can be obtained. Then, based on the rare earth element enrichment, the correlation between each mineralization influencing factor and rare earth element enrichment can be analyzed. Furthermore, based on the correlation between each mineralization influencing factor, at least one mineralization controlling factor can be identified from each mineralization influencing factor.

[0043] Finally, the characteristics of the ore-forming rock mass are correlated with the main controlling factors of ore formation, and integrated according to the preset ore-forming condition template to obtain the ore-forming conditions of ion adsorption type rare earth minerals.

[0044] The ion-adsorption type rare earth mineral identification method provided in this invention obtains the ore-forming rock mass characteristics of known ion-adsorption type rare earth minerals from multiple dimensions, including diagenetic age detection and elemental information determination. This ensures the integrity and reliability of the ore-forming rock mass characteristics. By analyzing the relationship between various mineralization influencing factors and rare earth element enrichment, the method can comprehensively determine the main mineralization controlling factors of known ion-adsorption type rare earth minerals from multiple perspectives, improving the accuracy and reliability of the main mineralization controlling factors. Furthermore, it ensures the reliability and accuracy of the mineralization conditions constructed based on the ore-forming rock mass characteristics and the main mineralization controlling factors. On this basis, the method identifies whether a target area is a potential mineralization target area for ion-adsorption type rare earth minerals based on the mineralization conditions, improving the accuracy and reliability of the identification results.

[0045] Optionally, the ore-forming rock mass characteristics include diagenetic age and rock mass elemental information; the step of performing feature detection based on the diagenetic age-detected sample and the elemental information-determined sample to obtain the ore-forming rock mass characteristics of the known ion-adsorption type rare earth ore includes: The diagenetic age of the sample was determined by performing diagenetic age analysis to obtain the diagenetic age of the known ion-adsorption type rare earth mineral. The sample for elemental information determination is subjected to compositional analysis to obtain the rock mass elemental information of the known ion adsorption type rare earth ore. The rock mass elemental information includes at least major element information as well as rare earth and trace element information.

[0046] Specifically, major elements, also known as constant elements, refer to elements with relatively high content in the sample for elemental information determination; major element information refers to information such as the content and proportion of major elements. For example, the major element information includes: content information of silicon dioxide (SiO2), content information of aluminum oxide (Al2O3), Rittmann index (σ), basicity ratio (AR), Sande index (A / CNK), and rock consolidation index (SI).

[0047] Specifically, trace elements refer to elements with low content in the sample for elemental information determination; rare earth and trace element information refers to information such as the content and proportion of trace elements and / or rare earth elements. For example, the rare earth and trace element information includes: the content information of total rare earth elements (∑REE), the content information of light rare earth elements (∑LREE), the rare earth element separation index ((La / Yb)n), the samarium / neodymium ratio ((Sm / Nd)n), the europium anomaly (δEu), and the cerium anomaly (δCe).

[0048] In practical applications, the diagenetic age of samples is measured to determine the diagenetic age of known ion-adsorption rare earth minerals, and the elemental composition of the samples is analyzed to determine the major element information, as well as the rare earth and trace element information of known ion-adsorption rare earth minerals.

[0049] In this embodiment of the invention, the characteristics of the ore-forming rock mass are determined from multiple dimensions, including diagenetic age, major elements, trace elements, and rare earth elements, which ensures the comprehensiveness of the characteristics of the ore-forming rock mass and improves the accuracy of the characteristics of the ore-forming rock mass.

[0050] Optionally, the element information determination samples include multiple types of determination samples. For example, the element information determination samples include mineral composition detection samples, major element detection samples, trace element detection samples, rare earth element detection samples, and total rare earth content detection samples of weathered rock layers, etc., and the number of each type of determination sample is at least one.

[0051] Optionally, the step of performing compositional analysis on the sample for determining the elemental information to obtain the rock mass elemental information of the known ion-adsorption type rare earth ore includes: The mineral composition of the sample was analyzed to obtain the mineral composition information of the known ion-adsorption type rare earth ore. Based on the mineral composition information, the major elements, trace elements and rare earth elements contained in the known ion adsorption type rare earth ore are determined. The major elements in the sample are detected to determine the major element information of the known ion-adsorption type rare earth ore. The trace elements in the trace element detection sample are detected, and the rare earth elements in the rare earth element detection sample and the total rare earth content in the weathered rock layer are detected, to determine the rare earth and trace element information of the known ion adsorption type rare earth ore.

[0052] Specifically, samples for mineral composition analysis can be thin slices or smooth sheets made from ground rock (ore).

[0053] In practical applications, the mineral composition of the sample can be analyzed under a polarizing microscope or a reflecting microscope to obtain the mineral composition information of the known ion-adsorption rare earth ore. This mineral composition information includes at least one mineral component, as well as the content, ratio, and structural characteristics of each mineral component. In other words, comprehensive composition analysis is performed on the sample under a polarizing microscope or a reflecting microscope to identify its mineral composition, content, ratio, and structural characteristics.

[0054] Based on the mineral composition information of known ion-adsorption type rare earth minerals, the major and trace elements contained in the known ion-adsorption type rare earth minerals are determined from the content, ratio, and structural characteristics of each mineral component. The rare earth elements in each mineral component of the known ion-adsorption type rare earth minerals are then identified as the rare earth elements contained in the known ion-adsorption type rare earth minerals.

[0055] For the major elements contained in known ion-adsorption rare earth ores, the major elements in the sample can be detected using X-ray fluorescence spectrometry, employing at least one of the following methods: gravimetric method, volumetric method, and inductively coupled plasma atomic emission spectrometry (ICP-AES), to determine the major element information of the known ion-adsorption rare earth ores. Among these methods, using gravimetric, volumetric, or ICP-AES methods for major element detection can reduce errors and improve the accuracy of major element detection.

[0056] For the rare earth elements and trace elements contained in known ion-adsorption type rare earth ores, inductively coupled plasma mass spectrometry (ICP-MS) can be used to detect each trace element in the trace element detection sample, and ICP-MS can also be used to detect the rare earth elements in the rare earth element detection sample and the total rare earth element detection sample of the weathered rock layer, thereby determining the rare earth and trace element information of the known ion-adsorption type rare earth ores. Using ICP-MS for rare earth and trace element detection can improve detection accuracy, thereby improving the accuracy of rare earth and trace element information.

[0057] Optionally, the number of samples for diagenetic age testing is at least one; The step of performing diagenetic age testing on the diagenetic age test sample to obtain the diagenetic age of the known ion-adsorption type rare earth mineral includes: Zircon uranium-lead dating was performed on each of the aforementioned diagenetic age testing samples to obtain the corresponding age values ​​for each of the aforementioned diagenetic age testing samples; Based on a first set age value, abnormal age values ​​among the age values ​​are filtered to obtain at least one filtered age value, wherein the first set age value is the lead-206 / uranium-238 age value. Using the first set age value and the second set age value, at least one target age value is determined from each of the filtered age values, wherein the second set age value is the lead-207 / uranium-235 age value; Based on the target age values, the diagenetic age of the known ion-adsorption type rare earth mineral is determined.

[0058] Specifically, the zircon uranium-lead dating process includes at least zircon sorting, target preparation, zircon cathodoluminescence imaging, and zircon isotope analysis; the testing instrument for zircon uranium-lead dating includes an inductively coupled plasma mass spectrometer (ICP-MS); the testing environment for zircon uranium-lead dating is: temperature of 20°C to 25°C and humidity of 40% to 45%. The ICP-MS can be a conventional ICP-MS and / or a laser ablation ICP-MS.

[0059] In practical applications, zircon uranium-lead (ZU-L) dating samples can be used for diagenetic age determination. Each ZU-L dating sample was analyzed using inductively coupled plasma mass spectrometry (ICP-MS). Helium was used as the carrier gas for the ablation material during the analysis, and standard analytical procedures were followed to obtain the corresponding age values ​​for each diagenetic age determination sample. The data obtained during the experiment were corrected for isotope ratios using a constant-pressure simulation method to eliminate the influence of common lead.

[0060] Furthermore, based on the age values ​​corresponding to the samples from each diagenetic age, statistical analysis of the lead-206 (206Pb) / uranium-238 (238U) ages revealed that due to the complex structure and fine grains of zircon, including cracks, inclusions, and remnants of old zircon cores, the laser beam used for zircon uranium-lead dating could not completely avoid these areas, resulting in multiple age values ​​deviating from the concordance curve. Therefore, these age values ​​deviating from the concordance curve, i.e., anomalous age values, need to be removed, and the remaining age values ​​are the filtered age values.

[0061] From the filtered age values, the age values ​​closest to those based on lead-207 (207Pb) / uranium-235 (235U) and 206Pb / 238U ages are selected as target age values, where the similarity characterization deviation is less than a set age threshold. Then, the average or weighted sum of the target age values ​​is used as the diagenetic age of known ion-adsorption type rare earth minerals.

[0062] In this embodiment of the invention, by performing zircon uranium-lead dating, the age value corresponding to the diagenetic age test sample can be obtained quickly and accurately; by checking and removing outliers based on the first set age value, the interference of invalid data on the final result can be avoided; and by combining the second set age value, a reliable target age value can be selected, thereby determining the diagenetic age of known ion adsorption type rare earth minerals. From the aspects of data source screening and data quality, the accuracy of diagenetic age is greatly improved.

[0063] Optionally, the multiple mineralization influencing factors include at least bedrock properties, topography, weathering and leaching, and climate and vegetation factors; Based on the rare earth element enrichment of the known ion-adsorption type rare earth ore, the main controlling factors of mineralization of the known ion-adsorption type rare earth ore are determined from multiple mineralization influencing factors, including: Based on the rare earth element enrichment in different rock strata in the known ion-adsorption type rare earth ore, the first influence data of the bedrock properties on rare earth element enrichment is determined. The first influence data includes the degree of influence of the different rock strata on the rare earth element enrichment. Based on the rare earth element enrichment in different topographic regions of the known ion-adsorption type rare earth ore, a second influence data on the rare earth element enrichment of the topography is determined. The second influence data includes the degree of influence of the different topographic regions on the rare earth element enrichment. Based on the rare earth element enrichment of different weathering layers in the known ion-adsorption rare earth ore and the rare earth element enrichment of different leaching types in the known ion-adsorption rare earth ore, a third influence data on the rare earth element enrichment of the weathering and leaching process is determined. The third influence data includes the degree of influence of each weathering layer on the rare earth element enrichment and the rare earth element distribution pattern corresponding to each leaching type region. Based on the climate of the distribution area of ​​ion-adsorption type rare earth minerals and the rare earth element enrichment in different vegetation cover areas of the known ion-adsorption type rare earth minerals, a fourth influence data on the rare earth element enrichment of the climate and vegetation factors is determined. The fourth influence data includes the degree of influence of the mineralization climate and each vegetation cover area. Based on the first influence data, the second influence data, the third influence data, and the fourth influence data, the main controlling factors for mineralization of the known ion adsorption type rare earth ore are determined.

[0064] Specifically, the weathered layers of each rock mass include, from top to bottom, a humus layer, a clay layer, a sub-clay layer, a completely weathered layer, a strongly weathered layer, and a weakly weathered layer.

[0065] Regarding bedrock properties: Obtain the rare earth element enrichment in different rock strata of known ion-adsorption type rare earth minerals, and then analyze the correlation between bedrock properties and rare earth element enrichment based on the rare earth element enrichment in different rock strata, that is, determine the degree of influence of different rock strata on rare earth element enrichment.

[0066] For example, the first influencing data is the difference in the distribution of mineralization points in different lithological distribution areas, among which the feldspar distribution area has greater mineralization potential.

[0067] Regarding topography and geomorphology: the enrichment of rare earth elements in different topographic and geomorphological regions of known ion-adsorption type rare earth mines can be obtained. Then, based on the enrichment of rare earth elements in different topographic and geomorphological regions, the correlation between topography and geomorphology and rare earth element enrichment can be analyzed, that is, the degree of influence of different topographic and geomorphological regions on rare earth element enrichment can be determined.

[0068] For example, different topographic regions can include the top of a hillside, the upper part of a hillside, the middle part of a hillside, and the lower part of a hillside. If the total rare earth element (REE) content in different topographic regions is measured and determined to follow the pattern of the middle part of the hillside > the lower part of the hillside > the upper part of the hillside > the top of the hillside, then the second influencing factor is that on the same hillside with significant elevation differences within a small area, geomorphological features affect the enrichment degree of REE elements, with the middle and lower parts of the hillside being more conducive to REE enrichment.

[0069] Regarding weathering and leaching: A well-developed rock mass weathering profile is divided from top to bottom into multiple rock mass weathering layers, including humus layer, clay layer, sub-clay layer, completely weathered layer, strongly weathered layer, and weakly weathered layer. Based on this, the rare earth element (REE) enrichment of different rock mass weathering layers and different leaching type regions in known ion-adsorption type rare earth deposits can be obtained. Then, based on the REE enrichment of different rock mass weathering layers and different leaching type regions, the correlation between weathering and leaching and REE enrichment is analyzed, that is, the degree of influence of different rock mass weathering layers on REE enrichment and the REE distribution pattern corresponding to each leaching type region are determined.

[0070] For example, the third impact data includes: gentle landform impact data and steep landform impact data.

[0071] Data on the influence of gentle topography include: the weathered rock layer and topsoil layer of the wide and gentle plateau at the summit are relatively thick, mainly leached vertically, with rare earth elements (REEs) exhibiting a convex distribution pattern in the vertical direction; the slope near the summit is affected by surface runoff, resulting in a thin topsoil layer, and the weathered rock layer is subjected to both vertical and horizontal leaching, with REEs exhibiting an upward convex distribution pattern in the vertical direction; the slightly steep slope in the middle is affected by strong surface runoff, resulting in an extremely thin topsoil layer, and the weathered rock layer is subjected to both vertical and horizontal leaching, with REEs exhibiting an L-shaped distribution pattern in the vertical direction; the plateau in the middle of the slope has a relatively thick topsoil layer, and the weathered rock layer is subjected to both vertical and horizontal uniform leaching, with REEs exhibiting a wave-like distribution pattern in the vertical direction.

[0072] Data on the impact of steep topography: The middle section of the steep slope experiences intense erosion, leaving almost no topsoil. The weathered rock layer is subjected to both vertical and horizontal leaching, resulting in an L-shaped distribution of rare earth elements (REEs) vertically. The lower section of the steep slope has a thinner topsoil layer, and the weathered rock layer is subjected to both vertical and horizontal leaching, resulting in an upward-convex distribution of REEs vertically. The lower plateau has a thicker topsoil layer, and the weathered rock layer is subjected to uniform vertical and horizontal leaching, resulting in a downward-convex distribution of REEs vertically. The lower steep slope also has a thinner topsoil layer, and the weathered rock layer is subjected to both vertical and horizontal leaching, resulting in a C-shaped distribution of REEs vertically.

[0073] Regarding climate and vegetation factors: The enrichment of rare earth elements (REEs) in areas with different vegetation cover in known ion-adsorption rare earth deposits can be obtained. Then, the correlation between climate and vegetation factors and REE enrichment in the distribution areas of ion-adsorption rare earth deposits and the REE enrichment in areas with different vegetation cover in known ion-adsorption rare earth deposits can be analyzed, i.e., determining the degree of influence of mineralization climate and areas with different vegetation cover. Specifically, the mineralization climate can form the climate of ion-adsorption rare earth deposits, that is, the climate of the distribution areas of ion-adsorption rare earth deposits.

[0074] For example, the fourth influencing factor is: the distribution area of ​​ion-adsorption type rare earth deposits is warm and humid, and these deposits are mainly distributed in subtropical and tropical climate zones; vegetation cover affects the intensity of leaching and weathering layer preservation. In areas with high vegetation cover, vertical leaching is mainly uniform precipitation, and the weathering layer is relatively well preserved. In areas with low vegetation cover, vertical leaching is mainly uneven and intense, and the upper weathering layer is severely lost, which is not conducive to the enrichment and preservation of rare earth elements. Climate and vegetation cover indicate regional prospecting directions that are prone to the formation of weathering ion-adsorption type rare earth deposits.

[0075] Furthermore, the first, second, third, and fourth impact data were analyzed to determine the main controlling factors of mineralization in known ion-adsorption type rare earth minerals.

[0076] In this embodiment of the invention, by analyzing the relationship between each mineralization influencing factor and rare earth element enrichment, multiple types of influencing data are obtained, and then the main mineralization controlling factors are determined based on the multiple types of influencing data, thereby improving the comprehensiveness and accuracy of the main mineralization controlling factors.

[0077] Optionally, the step of constructing the mineralization conditions for the ion-adsorption type rare earth deposit based on the characteristics of the ore-forming rock mass and the main controlling factors of mineralization includes: Based on the characteristics of the ore-forming rock mass and the main controlling factors of mineralization, the prospecting indicators and mineralization elements of the ion adsorption type rare earth deposit are extracted. Based on the main controlling factors of mineralization, the prospecting indicators, and the mineralization elements, the mineralization conditions of the ion adsorption type rare earth deposit are constructed.

[0078] Specifically, mineral exploration indicators, also known as mineralization indicators, refer to the indicators that can form ion-adsorption type rare earth deposits; mineralization elements refer to the necessary factors for the formation of ion-adsorption type rare earth deposits.

[0079] In practical applications, after obtaining the characteristics of the ore-forming rock mass and the main controlling factors of ore formation, mineral exploration indicators and mineralization elements can be extracted from the characteristics of the ore-forming rock mass and the main controlling factors of ore formation. Furthermore, the main controlling factors of ore formation, mineral exploration indicators and mineralization elements can be analyzed to establish the mineralization conditions of ion adsorption type rare earth deposits.

[0080] For example, if the main controlling factors of mineralization include bedrock properties, topography, weathering and leaching, and climate and vegetation factors, then the mineralization conditions can be a combination of the main controlling factors, prospecting indicators, and mineralization elements. As shown in Table 1: the prospecting indicators and mineralization elements corresponding to bedrock properties constitute the first sub-mineralization condition; the prospecting indicators and mineralization elements corresponding to topography constitute the second sub-mineralization condition; the prospecting indicators and mineralization elements corresponding to weathering and leaching constitute the third sub-mineralization condition; and the prospecting indicators and mineralization elements corresponding to climate and vegetation factors constitute the fourth sub-mineralization condition. The first to fourth sub-mineralization conditions constitute the mineralization conditions.

[0081] Table 1

[0082] In this embodiment of the invention, by extracting prospecting indicators and mineralization elements from the characteristics of the ore-forming rock mass and the main controlling factors of mineralization, mineralization phenomena of ion-adsorption type rare earth minerals can be described more concisely. Then, based on the main controlling factors of mineralization, prospecting indicators and mineralization elements, mineralization conditions can be constructed. This can reduce the complexity of mineralization conditions while ensuring the comprehensiveness and accuracy of the mineralization conditions, thereby reducing identification energy consumption and improving the identification efficiency of ion-adsorption type rare earth minerals.

[0083] Optionally, the main controlling factors of mineralization include bedrock properties, topography, weathering and leaching, and climate and vegetation factors; The extraction of prospecting indicators and mineralization elements for the ion-adsorption type rare earth deposit based on the characteristics of the ore-forming rock mass and the main controlling factors of mineralization includes: Based on the characteristics of the ore-forming rock mass and the properties of the bedrock, mineral exploration indicators and regional tectonic elements of the ore-forming rock are determined; Based on the characteristics of the ore-forming rock mass and the topography, determine the geomorphic prospecting indicators and ore-forming elements; Based on the characteristics of the ore-forming rock mass and the weathering and leaching process, the prospecting indicators and ore-forming dynamics elements of the rock mass weathering profile are determined; Based on the characteristics of the ore-forming rock mass and the climate and vegetation factors, climate and vegetation prospecting indicators are determined. The mineralization indicators of the ore-forming rocks, the geomorphological mineralization indicators, the rock mass weathering profile mineralization indicators, and the climate and vegetation mineralization indicators constitute the mineralization indicators of the ion-adsorption type rare earth deposit, and the regional tectonic elements, the ore-forming elements, and the mineralization kinetic elements constitute the mineralization elements of the ion-adsorption type rare earth deposit.

[0084] In practical applications, correlation analysis can be performed on the characteristics of ore-forming rock masses and the properties of bedrock to extract ore-forming rock prospecting indicators and regional tectonic elements. Among them, ore-forming rock prospecting indicators are prospecting indicators corresponding to the properties of bedrock, and regional tectonic elements are ore-forming elements corresponding to the properties of bedrock.

[0085] For example, the prospecting indicators for ore-forming rocks are: granites with a high degree of magmatic evolution differentiation are the material basis for ion-adsorption type rare earth minerals; accessory minerals such as sphene and monazite formed during magmatic differentiation are one of the main sources of rare earth elements, and their distribution areas are favorable ore-forming lithological zones for ion-adsorption type rare earth minerals; regional tectonic elements are: the distribution area of ​​collisional granites is an important regional ore-forming tectonic predictor for ion-adsorption type rare earth minerals.

[0086] Correlation analysis can be performed on the characteristics of ore-forming rock masses and topography to extract geomorphic mineral exploration indicators and ore-forming elements. Among them, geomorphic mineral exploration indicators are mineral exploration indicators corresponding to topography, and ore-forming elements are mineral exploration elements corresponding to topography.

[0087] For example, geomorphological prospecting indicators are: on the same mountain with significant differences in altitude, geomorphological features affect the enrichment degree of rare earth elements, and the lower part of the gentler slope is more conducive to the enrichment of rare earth elements; ore-forming elements are: intermediate-acidic granite rock bodies rich in accessory minerals such as sphene, monazite, and xenotime are important predictive elements for the source of ore-forming materials in weathered ion adsorption type rare earth deposits.

[0088] Correlation analysis can be performed on the characteristics of ore-forming rock masses and weathering and leaching, thereby extracting prospecting indicators and mineralization dynamics elements from the weathering profile of the rock mass. Among them, the prospecting indicators of the weathering profile of the rock mass are prospecting indicators corresponding to weathering and leaching, and the mineralization dynamics elements are prospecting elements corresponding to weathering and leaching.

[0089] For example, the prospecting indicators of a weathering profile of a rock mass are as follows: a well-developed weathering profile of a rock mass is divided from top to bottom into a humus layer, a clay layer, a sub-clay layer, a completely weathered layer, a strongly weathered layer, and a weakly weathered layer. The vertical enrichment of rare earth elements is affected by factors such as vertical leaching, lateral leaching, topography, and the degree of development of weathering and alteration layers. The completely weathered layer is a favorable stratum for the enrichment of rare earth elements. The mineralization kinetics are as follows: external physical, chemical, and biological weathering processes are important predictive elements for the secondary enrichment of rare earth elements in intermediate-acidic granite rock masses, forming ion adsorption type rare earth deposits.

[0090] Correlation analysis can be performed on the characteristics of ore-forming rock masses and climate and vegetation factors to extract climate and vegetation prospecting indicators, which are prospecting indicators corresponding to climate and vegetation factors.

[0091] For example, climate and vegetation are indicators for mineral exploration: areas with high vegetation coverage in subtropical and tropical rainy climate zones are conducive to the formation of weathered ion adsorption type rare earth deposits.

[0092] It should be noted that the determination of mineral exploration indicators and mineralization elements corresponding to each major mineralization controlling factor can be carried out simultaneously or in a certain order, and this invention does not impose any restrictions on this.

[0093] In addition, mineralization indicators such as ore-forming rocks, geomorphological mineralization indicators, rock mass weathering profiles, and climate and vegetation constitute the mineralization indicators for ion-adsorption type rare earth deposits; regional tectonic elements, ore-forming elements, and mineralization kinetic elements constitute the mineralization elements for ion-adsorption type rare earth deposits.

[0094] For example, the prospecting indicators and metallogenic elements corresponding to each major metallogenic factor are shown in Table 2.

[0095] Table 2

[0096] In this embodiment of the invention, by determining simplified mineral exploration indicators and mineralization elements from the perspective of multiple mineralization controlling factors, and combining multiple mineralization indicators and various mineralization elements to construct mineralization conditions, the accuracy and simplification of mineralization conditions are improved.
