Zinc Leaching tank

Zinc Pressure Leaching Process(ZPL) is the most advanced Zinc leaching technology in the world. During pressure leaching process, the Zn sulfide in concentrate will be turned into Zn Sulfate conditioned by proper temperature, acid amount and oxygen pressure etc. Then the Zn Sulfate solution will be precipitated and electro-winned to produce Zn; The S in concentrate is turned into elemental S in residue which can be further purified as a S product for sale.
