Description

TECHNICAL FIELD

[0002] Laterite nickel ore is a mineral resource mainly produced in tropical and subtropical regions, and is mainly composed of nickel and cobalt, and usually composed of nickel oxide minerals, silicate minerals and a small amount of sulfide minerals.

[0031] Embodiments of the present application are described below in detail with reference to the accompanying drawings, wherein the same or similar numerals represent the same or similar elements or elements having the same or similar functions throughout the accompanying drawings. The embodiments described below by reference to the accompanying drawings are exemplary and are only used to explain the present application and cannot be understood as a limitation of the present application. On the contrary, the embodiments of the present application include all changes, modifications and equivalents falling within the spirit and scope of the appended claims.

[0032] As shown in Figure 1 , Figure 2 and Figure 3 , the embodiments of the present application propose a system for mechanical mining and hydraulic slurry-making of laterite nickel ore, comprising: a mining system 1 and a slurry-making system 2. The mining system 1 comprises: a mining device 11 and a mineral material transportation device 12; the slurry-making system 2 comprises: a working platform 21, a washing device 22 and a mineral slurry conveying device 23. Further, the working platform 21 comprises: an adjacent bearing platform 211 and a discharge washing area 212.

[0033] The mining device 11 is used to mine mineral materials in a laterite nickel ore stope 13, and the mineral material transportation device 12 is used to transport the mineral materials to the discharge washing area 212. The washing device 22 is arranged on the bearing platform 211 and is used to wash the mineral materials in the discharge washing area 212 to produce mineral slurry. The slurry inlet end of the mineral slurry conveying device 23 is connected to the slurry outlet end of the discharge washing area 212, and the mineral slurry conveying device 23 is used to convey the mineral slurry to a chrome separation device.

[0034] It can be understood that the mining device 11 mines mineral materials in the laterite nickel ore stope 13, and the mineral material transportation device 12 transports the mineral materials to the discharge washing area 212. The washing device 22 washes the mineral materials in the discharge washing area 212 to produce mineral slurry, and the mineral slurry conveying device 23 conveys the mineral slurry to the chrome separation device. Thus, through the cooperation of the mining system 1 and the slurry-making system 2, the mining and slurry-making of the laterite nickel ore are realized. At the same time, the working system moves the washing and slurry-making part of the hydraulic mining to the working platform 21 near the mechanical mining stope 13, realizing the effective integration of mechanical mining and hydraulic mining. Not only does it solve the problem of transportation distance in mechanical mining, but also solves the problem of flexibility in hydraulic mining, thereby combining the advantages of flexibility and on-site slurry-making cost, thereby effectively improving the economic benefits of laterite nickel ore mining.

[0035] It should be noted that the mining system 1 is used for mechanical mining in the stope 13, and the slurry-making system 2 is used for washing and slurry-making of the mineral materials mined by the mining system 1. The mining system 1 as the mining part in mechanical mining and the slurry-making system 2 as the washing and slurry-making part in hydraulic mining are effectively integrated to form a working system combining the advantages of flexibility and low transportation distance cost.

[0036] The mining equipment 11 is used for mining the ore in the red soil nickel mine 13, and the specific type of the mining equipment 11 can be set according to actual needs, and no limitation is made thereto. For example, the mining equipment 11 can include two excavators, and the two excavators perform mining operations in the mine 13.

[0037] The ore transportation equipment 12 is used for transporting the ore to the unloading washing area 212, and the specific type of the ore transportation equipment 12 can be set according to actual needs, and no limitation is made thereto. For example, the ore transportation equipment 12 can include four articulated trucks, and each excavator is configured with two articulated trucks, and the articulated trucks transport the ore mined by the excavators to the unloading washing area 212.

[0038] The operation platform 21 is arranged close to the mine 13 (for example, the average distance is 0.9 km), and is used for realizing ore slurry making, so as to save the ore washing link. Specifically, the bearing platform 211 is used for arranging the washing equipment 22, the unloading washing area 212 is used for containing the ore mined by the mining system 1, and cooperates with the washing equipment 22 to form the ore slurry.

[0039] The specific type of the bearing platform 211 and the unloading washing area 212 can be set according to actual needs, and no limitation is made thereto. For example, the bearing platform 211 is a platform with a shape close to a cuboid, with a length of about 10 meters and a width of about 4 meters; the unloading washing area 212 is a concave area with a shape close to a cuboid, with a length comparable to that of the bearing platform 211, a width of about 5 meters, and a height difference of about 2.5 meters from the bearing platform 211. The unloading washing area 212 and the bearing platform 211 are connected by a slope with a small angle, and in actual use, accumulation may occur, which can be cleaned according to needs.

[0040] The washing equipment 22 is used for washing the ore in the unloading washing area 212 to generate the ore slurry, and the specific type of the washing equipment 22 can be set according to actual needs, and no limitation is made thereto. For example, the washing equipment 22 can be a high-pressure water gun, etc. In the unloading washing area 212, the distance between the ore pile to be washed and the gun mouth on the bearing platform 211 is kept to be more than 3 meters, so as to avoid that the high-pressure water splashes onto the bearing platform 211 due to too close distance.

[0041] The ore slurry conveying device 23 is used for conveying the ore slurry to the chrome separation device, and the specific type of the ore slurry conveying device 23 can be set according to actual needs, and no limitation is made thereto.

[0042] The chrome separation device is used for screening the chromite to form the final purified ore slurry, and the specific type of the chrome separation device can be set according to actual needs, and no limitation is made thereto. The chrome separation device is arranged in a chrome separation workshop.

[0043] For example, Figure 1 and Figure 3As shown, in some embodiments, the slurry conveying device 23 includes: a slurry collection tank 231 and a slurry pump 232. The slurry inlet end of the slurry collection tank 231 is connected to the slurry outlet end of the unloading and flushing zone 212, and the height of the slurry collection tank 231 is less than the height of the unloading and flushing zone 212. The slurry inlet end of the slurry pump 232 is connected to the slurry outlet end of the slurry collection tank 231, and the slurry outlet end of the slurry pump 232 is connected to the slurry inlet end of the chromium extraction device.

[0044] Understandably, since the inlet end of the slurry collection tank 231 is connected to the outlet end of the unloading and flushing zone 212, and the height of the slurry collection tank 231 is less than the height of the unloading and flushing zone 212, the slurry generated in the unloading and flushing zone 212 can flow by gravity to the slurry collection tank 231 using the height difference. Furthermore, since the inlet end of the slurry pump 232 is connected to the outlet end of the slurry collection tank 231, and the outlet end of the slurry pump 232 is connected to the inlet end of the chromium beneficiation unit, the slurry pump 232 can pressurize and transport the slurry in the slurry collection tank 231 to the chromium beneficiation unit. Thus, through the cooperation of the slurry collection tank 231 and the slurry pump 232, the transportation of slurry from the unloading and flushing zone 212 to the chromium beneficiation unit is realized, ensuring the efficient operation of the system.

[0045] It should be noted that the slurry collection tank 231 is used to contain the slurry generated in the unloading and washing area 212. The specific type of the slurry collection tank 231 can be set according to actual needs and there is no restriction. For example, the slurry collection tank 231 can be a box structure for temporary storage of slurry. The box size is 6m×4m×2m and it is welded from steel plates.

[0046] The slurry pump 232 is used for pressurizing and conveying slurry. The specific type of slurry pump 232 can be set according to actual needs and is not limited thereto. However, the slurry pump 232 needs to take into account fine impurities in the slurry to ensure the durability of the equipment. Specifically, the equipment parameters are selected as follows: maximum solid particle size 30mm, maximum flow rate 900m³ / h. 3 / h, solid weight concentration 15%-25%, maximum head 148m.

[0047] like Figure 1 and Figure 3 As shown, in some embodiments, the slurry conveying device 23 further includes a trench 233, which is inclinedly disposed between the unloading and washing zone 212 and the slurry collection tank 231. The upper end of the trench 233 is connected to the slurry outlet end of the unloading and washing zone 212, and the lower end of the trench 233 is connected to the slurry inlet end of the slurry collection tank 231. The bottom plate of the unloading and washing zone 212 extends downwards at an incline near the slurry outlet end of the unloading and washing zone 212.

[0048] It can be understood that, due to the bottom plate of the unloading and washing area 212 extends downwardly and obliquely in the direction close to the pulp outlet end of the unloading and washing area 212, the pulp generated in the unloading and washing area 212 can flow to the pulp outlet end by itself, and due to the groove 233 is obliquely arranged between the unloading and washing area 212 and the pulp collecting tank 231, and the upper end of the groove 233 is connected with the pulp outlet end of the unloading and washing area 212, and the lower end of the groove 233 is connected with the pulp inlet end of the pulp collecting tank 231, the pulp at the pulp outlet end of the unloading and washing area 212 can flow to the pulp collecting tank 231 along the groove 233. Thus, by the oblique arrangement of the bottom plate of the unloading and washing area 212 and the oblique arrangement of the groove 233, the pulp in the unloading and washing area 212 flows to the pulp collecting tank 231 by itself, and thus the low-cost pulp conveying operation is realized.

[0049] It should be noted that the groove 233 is used for guiding the pulp, and the specific type of the groove 233 can be set according to actual needs, which is not limited, for example, the groove 233 is an inclined groove body arranged between the unloading and washing area 212 and the pulp collecting tank 231, and the overall slope of the groove 233 is greater than 15 degrees to ensure that the pulp can flow smoothly. The groove 233 can have a bending part, and the angle of the bending part should not be too large, and the pulp flows more smoothly when the angle is not greater than 100 degrees after testing.

[0050] In some embodiments, the pulp conveying device 23 further comprises a screen, and the screen is arranged at the pulp inlet end of the pulp collecting tank 231, and the screen has screen holes with a preset diameter.

[0051] It can be understood that, due to the screen is arranged at the pulp inlet end of the pulp collecting tank 231, and the screen has screen holes with a preset diameter, the screen can screen out impurities in the pulp with a diameter greater than the preset diameter, so as to ensure the purity of the pulp, and at the same time, avoid damage to the pulp pump 232 due to large impurities.

[0052] It should be noted that the screen is used for screening and filtering the pulp at the pulp inlet end of the pulp collecting tank 231, and the specific type of the screen can be set according to actual needs, which is not limited, for example, the screen can be welded by steel bars, the gap between the steel bars is 30 mm (the preset diameter), and branches and impurities larger than 30 mm are filtered.

[0053] As shown in Figure 1 and Figure 2 In some embodiments, the work platform 21 further comprises a gravel accumulation area 213, and the gravel accumulation area 213 is arranged on the side of the unloading and washing area 212 away from the bearing platform 211, and the gravel accumulation area 213 is used for accommodating gravel in the mineral material.

[0054] It can be understood that, since the gravel accumulation area 213 is arranged on the side of the unloading and washing area 212 away from the bearing platform 211, the gravel accumulation area 213 is convenient to accommodate residual gravel after washing of the mineral material in the unloading and washing area 212, thereby leaving washing space for the unloading and washing area 212 and ensuring efficient operation of the system.

[0055] It should be noted that the gravel accumulation area 213 is used to accommodate gravel in the mineral material, and the specific type of the gravel accumulation area 213 can be set according to actual needs, which is not limited, for example, the gravel accumulation area 213 is in a platform structure, and the upper elevation is equivalent to that of the bearing platform 211, and a long strip shape is relatively suitable for throwing gravel out of the side; the gravel accumulation area 213 and the unloading and washing area 212 are transitioned by a natural slope; and the side of the gravel accumulation area 213 away from the unloading and washing area 212 is a steep slope with a large height difference, which has a large space for stacking gravel.

[0056] As shown in FIGS. Figure 1 , Figure 2 and Figure 3 , in some embodiments, the slurry making system 2 further comprises a turning equipment 24, which is arranged in the unloading and washing area 212 and is used to turn the mineral material and transport gravel to the gravel accumulation area 213.

[0057] It can be understood that the turning equipment 24 turns the mineral material, thereby facilitating washing of the mineral material and improving slurry making efficiency, and at the same time, the turning equipment 24 transports gravel to the gravel accumulation area 213, thereby leaving washing space for the unloading and washing area 212 and ensuring efficient operation of the system.

[0058] It should be noted that the turning equipment 24 is used to turn the mineral material and transport gravel to the gravel accumulation area 213, and the specific type of the turning equipment 24 can be set according to actual needs, which is not limited, for example, the turning equipment 24 can be an excavator, which is arranged in the unloading and washing area 212 and turns the mineral material, and after the mineral heap in the unloading and washing area 212 is separated from the slurry by high-pressure water column washing, gravel is left below the unloading and washing area 212, and the excavator concentrates on throwing the residual gravel to the gravel accumulation area 213 during production gap time.

[0059] The fine ore is relatively easy to wash and make slurry, and basically does not need to be turned by the excavator, while the gravel-containing ore is relatively slow to wash and make slurry, and needs to be turned by the excavator multiple times.

[0060] It is relatively suitable that the excavator of the unloading and washing area 212 and the water column jetted from the gun of the bearing platform 211 maintain an angle of 30-60 degrees.

[0061] In some embodiments, the flushing device 22 comprises a water source, a water pump, and a plurality of water guns. The water inlet end of the water pump is connected to the water outlet end of the water source, and the water inlet end of each water gun is connected to the water outlet end of the water pump. The water outlet end of each water gun faces the unloading and flushing area 212.

[0062] It can be understood that, since the water inlet end of the water pump is connected to the water outlet end of the water source, and the water inlet end of each water gun is connected to the water outlet end of the water pump, and the water outlet end of each water gun faces the unloading and flushing area 212, the water pump can pressurize and deliver the flushing water from the water source to each water gun, and then spray the flushing water to the unloading and flushing area 212 by using each water gun, so as to form the ore material into the ore slurry.

[0063] It should be noted that the water source is used to provide flushing water, and the specific type of the water source can be set according to actual needs, which is not limited. For example, the water source can be mine production water, which can be obtained from external river water supply or thickening pool backwater of a chrome selection workshop.

[0064] The water pump is used to pressurize and deliver the flushing water, and the specific type of the water pump can be set according to actual needs, which is not limited.

[0065] The water gun is used to spray the high-pressure water delivered by the water pump to the ore material in the unloading and flushing area 212, and the specific type of the water gun can be set according to actual needs, which is not limited. For example, the water gun can be composed of a gun head, a rotating part, and an operating handle. Four water guns are arranged on a base, and the base is placed at a position that is more than 0.5 meters away from the edge of the carrying platform 211, so as to prevent the base from sliding off the carrying platform 211.

[0066] As shown in FIG. 1, Figure 3 In some embodiments, the ore material transportation device 12 comprises at least one transportation vehicle, which is used to transport the ore material to the unloading and flushing area 212. One end of the unloading and flushing area 212 is provided with a barrier 214, and the barrier 214 is used to limit the transportation vehicle.

[0067] It can be understood that the transportation vehicle is used to transport the ore material to the unloading and flushing area 212, so as to realize the transportation and transfer of the ore material in the stope 13 to the unloading and flushing area 212. At the same time, since one end of the unloading and flushing area 212 is provided with the barrier 214, the barrier 214 can limit the transportation vehicle, so as to prevent the transportation vehicle from sinking into the lower recessed area when the ore material is unloaded.

[0068] It should be noted that the transportation vehicle is used to transport the ore material to the unloading and flushing area 212, and the specific type of the transportation vehicle can be set according to actual needs, which is not limited. For example, the transportation vehicle can be a articulated truck.

[0069] The barrier 214 is used for limiting the transport vehicle, and the specific type of the barrier 214 can be set according to actual needs, which is not limited.

[0070] In some embodiments, the operation system further comprises a power supply device, the power supply device comprises a fuel generator and a power conversion module, the power supply end of the fuel generator is connected with the power end of the power conversion module, and the power supply end of the power conversion module is connected with the power end of the flushing equipment 22 and the power end of the ore slurry conveying device 23 respectively.

[0071] It can be understood that, since the power supply end of the fuel generator is connected with the power end of the power conversion module, and the power supply end of the power conversion module is connected with the power end of the flushing equipment 22 and the power end of the ore slurry conveying device 23 respectively, the fuel generator can convey the generated electric energy to the power conversion module, and after the electric energy conversion of the power conversion module, the electric energy is conveyed to the flushing equipment 22 and the ore slurry conveying device 23, thereby ensuring the stable operation of the flushing equipment 22 and the ore slurry conveying device 23.

[0072] It should be noted that the fuel generator is used for generating electricity by using fuel, so as to realize flexible operation of the operation system and avoid being limited by the distribution of the power grid. The specific type of the fuel generator can be set according to actual needs, which is not limited. For example, the fuel generator can be a diesel generator, and the electric energy is supplied to the ore slurry pump 232, the water pump and the like. The diesel generator is selected to have a power of 800kw.

[0073] The power conversion module is used for converting the output electric energy of the fuel generator, so as to meet the different power demands of the equipment. The specific type of the power conversion module can be set according to actual needs, which is not limited.

[0074] In some embodiments, the operation system further comprises a plurality of lighting devices, the plurality of lighting devices are arranged on the stope 13 and the operation platform 21 respectively, and the power end of the lighting device is connected with the power supply end of the power conversion module.

[0075] It can be understood that, since the plurality of lighting devices are arranged on the stope 13 and the operation platform 21 respectively, and the power end of the lighting device is connected with the power supply end of the power conversion module, the lighting device can realize the lighting function by using the power supply of the power supply device, thereby meeting the lighting demand of the operation system, and further ensuring the high operation efficiency of the system.

[0076] It should be noted that the lighting device is used for lighting the operation site, and the specific type of the lighting device can be set according to actual needs, which is not limited.
