Description
Technical Field
The utility model relates to a desliming and leaching system of gold ores. The system is mainly used for treating gold ores containing easily-slimed minerals.
Background
Before the minerals enter the sorting process, firstly, the minerals are crushed and ground, and some mineral mud with the granularity less than 5-10 microns can be generated in the crushing and grinding processes. Meanwhile, gold ores include main gold-bearing minerals (flotation target minerals) such as pyrite, arsenopyrite, chalcopyrite, and galena, and gangue minerals such as talc, serpentine, chlorite, calcite, dolomite, sericite, kaolinite, montmorillonite, and feldspar, and metal oxide ores such as limonite and siderite. Gangue minerals and metal oxide minerals themselves are easily slurried into slimes. The slimes have poor floatability, can increase medicine consumption, deteriorate water quality, form bubble armor and have adverse effects on flotation indexes.
At present, aiming at the easily-slimed gold ore, in order to solve the problem of ore sliming, firstly, desliming is carried out in a spraying and flushing mode in the screening process, and the removal of fine slimes generated in the working processes of mining, transportation, crushing and the like can be realized. However, after the easily-slimed gold ore enters the ore grinding classification closed circuit system, a large amount of fine mud is produced again in the ore grinding treatment process of the ball mill, and the fine mud and the minerals which are not easily-slimed in the gold ore enter the flotation system together, so that the recovery rate of flotation operation is affected. And secondly, desliming is carried out by a cyclone before flotation, so that partial mineral mud before flotation can be removed. However, the materials (including the minerals which are easy to be slimed and difficult to be slimed) before floatation are ground, the granularity difference is not obvious, the desliming effect of the cyclone is poor, and the separation of the minerals which are easy to be slimed and difficult to be slimed is difficult to realize.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a desliming and leaching system for gold ores containing easily-slimed minerals, which not only can effectively solve the problem of fine mud removal in the ore grinding treatment process, but also can realize the effective separation of easily-slimed and difficultly-slimed minerals, realize the advanced sliming of the easily-slimed minerals and improve the total recovery rate of gold ores containing the easily-slimed minerals.
The technical scheme of the utility model is as follows:
the desliming and leaching system comprises a desliming cyclone, a thickener with an overflow port and a bottom flow port, a filter press, a belt conveyor, a leaching stirring tank, a first stirring tank with an overflow port and a second stirring tank with an overflow port, wherein the overflow port of the first stirring tank is connected with the feed port of the desliming cyclone through a pipeline, a pump tank and a slurry pump; the bottom flow port of the desliming cyclone is used for connecting an ore grinding and flotation system, the overflow product outlet of the desliming cyclone is connected with the feed inlet of the thickener through a pipeline, and the bottom flow port of the thickener is connected with the feed inlet of the filter press through a pipeline, a pump tank and a slurry pump; the filter cake discharge end of the filter press is connected with the feed inlet of the second stirring tank through a belt conveyor, and the overflow port of the second stirring tank is connected with the feed inlet of the leaching stirring tank through a pipeline, a pump tank and a slurry pump.
Preferably, the overflow port of the thickener and the filtrate port of the filter press are connected with the feed port of the first stirring tank through a pipeline, a pump tank and a slurry pump respectively.
Preferably, the position of the outlet of the ground product of the ball mill is higher than the position of the feed inlet of the first stirring tank; the overflow port of the first stirring tank is higher than the feed port of the pump tank connected with the first stirring tank.
Preferably, the overflow product outlet position of the desliming cyclone is higher than the feed inlet position of the thickener.
Preferably, the position of the underflow outlet of the thickener is higher than the position of the feed inlet of the pump tank to which the underflow outlet is connected; the overflow port of the thickener is higher than the feed port of the pump tank connected with the overflow port.
Preferably, the filtrate port of the filter press is located higher than the feed port of the pump tank to which the filtrate port is connected.
Preferably, the overflow port of the second stirring tank is higher than the feed port of the pump tank connected with the overflow port.
The utility model has the positive effects that:
the classification of hydrocyclones as desliming mechanisms is based on the principle of centrifugal sedimentation. Since the fine slime and coarse sand differ in particle size and density, they are subjected to different centrifugal forces. When ore slurry containing ore slurry enters into an ore feeding pipe by pressure or gravity and enters into a hydrocyclone along the tangential direction, coarse sand is subjected to larger centrifugal force and is thrown to the vicinity of the wall, and is discharged from a sand setting port at the bottom along with external spiral flow to become an underflow product with more solid particles, and the ore slurry is subjected to smaller centrifugal force due to smaller density, slow sedimentation speed and longer stay time in the spiral flow, so that the overflow product is finally obtained.
The utility model carries out a section of open-circuit pre-grinding treatment on the mud-containing gold ore ball mill, so that the mud-containing minerals in the mud-containing gold ore are finely ground in advance, the fine mud is separated by a cyclone, the fine mud is subjected to cyanidation leaching after sedimentation and dehydration, and the leaching rate of the fine mud separation to remove leaching is higher than the flotation recovery rate of the flotation treatment. Meanwhile, the fine mud does not enter a subsequent ore grinding classification closed circuit system and subsequent flotation operation, so that overgrinding of the fine mud is reduced, the processing load of subsequent ore grinding equipment is lightened, the ore grinding efficiency of the whole process is improved, and indexes such as recovery rate of subsequent flotation are improved. Thereby achieving the purpose of improving the recovery rate of the dressing and smelting of the mud-containing gold ore.
