Zinc is mined by more than 50 countries, including the U.S.A. The mines are usually underground but some new ones are the open pit type such as the one on the left. The zinc ore is rarely pure enough to be directly smelting. Zinc ores contain 5-15% zinc. To concentrate the ore it is crushed and then ground to separate the minerals. Typically, zinc concentrate contains 55% zinc with some copper, lead, and iron. That is done at the mine and then it's off to smelting.
