Zinc: smelting, producing and classification-Metalpedia

Zinc is found in the earth’s crust primarily as zinc sulfide (ZnS). Rarely is the ore, as mined, rich enough to be used directly by smelters; it needs to be concentrated. Zinc ores contain 5-15% zinc. To concentrate the ore, it is first crushed and then ground to enable optimal separation from the other minerals.

History, Deposits, and Production of Zinc

2020-3-30  Zinc ore is no longer mined in Germany today, and the zinc concentrations in the deposits are too low for cost-effective zinc extraction. The raw material for zinc extraction has therefore traveled a long way, for example, from Australia mostly by ship before it is processed into zinc metal in Germany.
