Description

Technical Field

[0001] The invention belongs to the technical field of process mineralogy, and in particular relates to a method for determining the gold interlocking relationship of a gold ore product. Background Art

[0002] Gold itself is stable in nature and is a good material for currency and jewelry. At the same time, due to its excellent physical and chemical properties, it is also widely used in industry. However, with the development and utilization of gold resources, the resources that are easy to mine and smelt are gradually exhausted, and the ores that are difficult to mine and process are gradually increasing, which puts higher requirements on the development and utilization of gold resources. Correspondingly, for the development of gold ore resources, the examination of the interlocking relationship of gold minerals under a certain grinding fineness is the primary work before the start of the mineral processing test, and the research results are the key data that directly guide the mineral processing process.

[0003] For the analysis of the intercalation relationship of gold, previous studies have mainly focused on physics (optical microscope, electron probe, MLA, etc.) and chemistry (mercury amalgamation, cyanidation, iodination, thiourea, EDTA, etc.). The previous method used mercury amalgamation to capture monomer gold. During the operation, because mercury is volatile, toxic and harmful gases will be generated during the experimental analysis process. At the same time, mercury is also prone to chemical reactions with some other metal minerals, which will lead to incomplete capture of monomer gold. In addition, mercury amalgamation has high requirements for samples, and there is a problem that fine-grained gold is difficult to effectively quantify. For the determination of intercalated gold, there are few previous studies, and most of them only examine leachable gold (monomer gold + sulfide intercalated gold + gangue intercalated gold). This cannot meet the existing actual needs, because as a process mineralogy study, especially for flotation technology, the main purpose is to determine the proportion of recoverable gold minerals, that is, monomer gold + metal sulfide encapsulated gold + metal sulfide intercalated gold, while gangue encapsulated gold and gangue intercalated gold are difficult to recover by flotation technology, and current scientific researchers need to provide accurate data. The previous means and test analysis level cannot match.

[0004] The biggest problem is whether the gold minerals found by pure physical methods are representative. The current samples are of low grade and complex material composition. Pure physical methods can only characterize the characteristics of the samples to a certain extent. Chemical analysis also has various drawbacks as mentioned above. At the same time, "phase crosstalk" runs through the entire analysis process. Therefore, a suitable method is needed in this field to provide reasonable and accurate data. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a method for determining the gold interlocking relationship of a gold ore product, which has the advantages of being reasonable and accurate, can effectively determine the interlocking relationship of gold in the gold ore product, and provide accurate data support for the rational use of the ore.

[0099]

[0100] The intercalation relationship of gold described in this method refers to the intercorrelation relationship between gold minerals and other minerals under a certain grinding fineness, mainly monomers (not intercorrelated with other minerals), intercorrelation (gold minerals intercorrelated with other minerals, exposed), inclusions (gold minerals are included in other minerals, not exposed) and gold adsorbed by carbon. This classification directly corresponds to the mineral processing technology, and it is not appropriate to adopt overly detailed divisions in geology, such as colloidal gold (gold in the form of colloidal particles) and smaller invisible gold (lattice gold, ionic gold, etc.). This type of gold mineral is generally present in carrier metal sulfides and can be directly determined as gold in the state of metal sulfide inclusions.
