Uses of Zinc Supply, Demand, Production, Resources

Sphalerite (zinc sulfide) is the primary ore mineral from which most of the world's zinc is produced, but a number of other minerals that do not contain sulfide contain zinc as a major component. Much of the early zinc production was from nonsulfide deposits; however, as these resources were exhausted, production shifted to sulfide deposits.

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 have a vitreous or pearly luster and are typically dirty brown or

The traditional approach to processing zinc, known as the roast leach electrowin (RLE) process has long been used to effectively process sulphide ores, but has limitations when it comes to more complex sulphide ores, and is not capable of processing other ore types. Additionally, the RLE approach produces SO2 gas, which requires fixation.

Nearly all zinc sulphide ores carry some lead; the western ores of zinc generally carry silver, and some of them carry both silver and gold. Pyrite, pyrrhotite, chalcopyrite, and galena are very commonly associated with sphalerite in sulphide deposits. The most common gangue minerals are quartz, calcite, and dolomite. Rhodochrosite and rhodonite are abundant in zinc ores at Butte, Montana.
