Mineral Ore Separation Equipment

Minerals are chalcopyrite, galena, sphalerite, and pyrite, pyrrhotite. Gangue minerals are garnet, calcite, quartz, plagioclase and diopside and so on. Galena and sphalerite crystals coarser, fine-grained chalcopyrite crystals, ore basic is easy to choose. Now plant using flotation process. In copper, lead, zinc flotation, because with xanthate as collector, chalcopyrite and galena floatability of very close, add sodium-activated sphalerite, plus a small amount of cyanide inhibition of iron mineralization Minerals.

Mineral Ore Separation Machine

Copper, lead, zinc concentrate mixed with lime slurry transferred into pH9 ~ 10, plus zinc sulfate with sodium cyanide inhibition of sphalerite, copper, lead and zinc minerals to achieve separation. Copper, lead separation, mixing potassium dichromate plus 90 to 100 minutes, adjusting the pH value of about 9 to 9.5, inhibition of lead floating copper, copper concentrate obtained. This should lead concentrate tailings, but the separation of copper, lead and zinc, some easy to float into the copper-lead-zinc concentrate mixture.mineral ore separation equipment

Separation of copper and lead, zinc and lead this part along with the suppression and into the lead concentrate. In order to ensure the quality of lead concentrate, zinc recovery increased, further removal of lead concentrate from mixed zinc minerals. Activation of zinc with copper sulfate minerals at this time, floating zinc inhibition of lead, zinc and lead concentrate respectively in the mine.

The process is characterized by:
(1) The ore minerals of secondary mineralization less so in the flotation separation, the suppression is the use of potassium dichromate method of lead float copper. (If the ore contains large amounts of secondary sulfide copper minerals, the copper ions will be activated galena, is difficult to continue with the inhibition of potassium dichromate, lead-time should be used to float copper cyanide inhibition of copper lead separation);
(2) copper ore in the mineral matter content than the lead content is low, so according to “float less suppression and more” principle, the separation of copper and lead used in lead-float copper suppression methods;
(3) the use of lead concentrate from the leak mixed solution of zinc minerals, both to improve the quality of lead concentrate to remove harmful impurities of zinc smelting, and also enhance the recovery of zinc.

In recent years, multi-metal sulfide ore flotation process has been greatly developed, and gradually promote the use of flotation process flotation process to replace; of complex polymetallic sulfide ores, with a more reasonable stage grinding stage sorting process ; separation operations, domestic and international law gradually extended SO2 (sulfurous acid method) until the cyanide process to replace the cyanide method, the method is perfected, the effect is well adapted to the requirements of environmental engineering; promote the use of selective fishing with good collector, such as diltiazem type collector, Z-200 No. (ethyl – dithiocarbamate isopropyl ester), or their combination with the xanthate, and achieved good results; Moreover, as the use of heating flotation , aerosol method and the electric field, magnetic field, high-energy radiation (γ-rays, ultraviolet, etc.) dealing with flotation agents, water, pulp and minerals, to improve the flotation separation also has been developed.

Integrated multi-metal ore separation technology is a technology turning waste into wealth, but also pay attention to environmental protection in today to reduce carbon emissions is an effective technique.
