Zinc Mining and Processing Everything you Need to Know

Zinc Mining and Processing Everything you Need to Know. 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 methods used today.
