Zinc Mining and Processing: Everything you Need to Know

Mar 7, 2014 ... Compared to tin mining, the history of zinc mining is relatively short. In the 18th century, it was discovered that sphalerite, or zinc sulfide, could be smelted into brass, resulting in the first patented techniques. Since then, the zinc industry has progressed to the current zinc mining process and production...

At around the same time, it was realised that the mineral sphalerite (zinc sulphide) could also be used for the same purposes, and new techniques for making brass directly from zinc were patented. By 1779, Bristol brass was in great demand, and Shipham and Rowberrrow became the centre of the zinc mining industry.

Zinc ore and mines | Minerals and mines | Foundations of the Mendips

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 (ZnCO3), known as calamine or smithsonite. It generally occurs as rounded, crystalline crusts or granular,...

Zinc mining - Wikipedia

Zinc mining is the process by which mineral forms of the metal zinc are extracted from the earth through mining. A zinc mine is a mine that produces zinc metal. Some mines produce primarily zinc, but some mines produce zinc as a side-product of some metal that has a higher concentration in the ore. Most zinc mines...
