Lead and Zinc Smelting Industry Description and Practices Lead and zinc can be produced pyrometal-lurgically or hydrometallurgically, depending on the type of ore used as a charge. In the pyromet-allurgical process, ore concentrate containing lead, zinc, or both is fed, in some cases after sin-tering, into a primary smelter. Lead concentra-
The established lead-zinc ore flotation processing scheme is to add zinc sulphate ZnSO4 to the grind to control metal ion activation sphalerite depression. Often metabisulphide or other sulphidation chemicals are added with the zinc sulphate for iron sulphide mineral depression.
1 Lead-zinc sulfide ore 1. Beneficiation process of lead-zinc sulfide ore The main constituent minerals of lead sulphide ore are galena and sphalerite, all of which are primary ore. Galena has good floatability. In most lead-zinc mines, zinc is higher than lead.
