2ZnS 3O 2ZnO SO2 (1) US EPAZinc is found in the earth's crust primarily as zinc sulfide (ZnS). Primary uses for zinc include galvanizing of all forms of steel, as a constituent of brass, for electrical conductors, vulcanization of rubber and in primers and paints. Most of these applications are highly dependent upon zinc's resistance to corrosion and its light weight ...

Zinc Ore Separate Sphalerite is a zinc sulfide mineral with a chemical composition of (Zn,Fe)S. It is found in metamorphic, igneous, and sedimentary rocks in many parts of the world. Sphalerite is the most commonly encountered zinc mineral and the world's most important ore of zinc..
The role of sodium sulphide in amine flotation of silicate ...The replacement, even partial, of sodium sulphide by other pH regulating agents, such as sodium carbonate and sodium hydroxide, decreases the recovery and grade of the zinc concentrates, as shown in figures 4 and 5, for hemimorphite [11]. In the pH range of zinc silicates flotation, the predominant species of sodium sulphide dissociation is HS.
zinc ore flotation The established leadzinc 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.
