mining process of zinc ore
Zinc ore occurs in two types of deposit: as primary zinc ore in thin veins known as rakes, or a secondary deposit formed by weathering of the primary mineral veins. Zinc ore is most commonly found as zinc carbonate (ZnCO 3), known as calamine or smithsonite. It generally occurs as rounded, crystalline crusts or granular, honeycombed masses that ...
