What is zinc used for mining?
History. Zinc deposits have been exploited for thousands of years, with the oldest zinc mine, located in Rajasthan, India established nearly 2000 years BP. Approximately 20% of the world’s zinc is used in the production of brass, where zinc is alloyed with copper in between ratios of 20-40% zinc.
What was zinc first used for?
brass
Zinc was first used in China by at least A.D. 1637, and was mined and smelted in India even earlier — by the ninth century B.C., at least, according to the 2006 research published in the journal Ancient Asia. At first, ancient people used zinc ores mostly to make brass (an alloy of copper with zinc).
How is zinc used in medicine?
