Flotation is a method that is widely used in gold ore processing plant to process the rock gold commonly used in dealing with highly floatable sulfide minerals containing gold ore Flotation process can maximum enrich gold to the sulfide mineral tailings can be abandoned directly the cost of processing plant is low 80 of Chinas rock

Zinc processing Zinc processing Ores Zinc ores are widely distributed throughout the world although more than 40 percent of the world’s output originates in North America and Australia The common zinccontaining minerals are the zinc sulfide known as zinc blende or sphalerite ZnS a ferrous form of zinc blende known as marmatite ZnFeS and a zinc carbonate known as calamine

The heap leaching cyanidation method is that goldcontaining lowgrade ore is crushed or agglomerated into a lump of 310 mm stacked on an impermeable bottom pad and sprayed from the top of the heap with a cyanide solution to dissolve the gold in the ore The goldbearing precious liquid percolates out of the mine heap and pools into the

Preconcentration of coarse 350 – 500 micron sulphideassociated gold ore using the InLine Pressure Jig is required to reject gangue from the high value IPJ a classic preconcentration device is effective in gangue rejection prior to further processing of valuable goldbearing material Other turnkey modular systems for preconcentrating coarse sulphidegold ores include

During the cyanidation process of ore the surface of gold particles is in contact with the cyanide ore slurry and the surface of gold particles may form sulfide film peroxide film such as calcium peroxide film oxide film insoluble cyanide film etc Surface passivation significantly reduces the oxidation and leaching speed of the gold

The gold ore must be pretreated to oxidize sulfide minerals associated with gold and to remove other minerals and chemical compounds that interfere in the cyanidation leaching process
