History, Deposits, and Production of Zinc

2020-3-30  The Importance of Zinc in History. The Romans under the rule of Emperor Augustus (20 BC to 14 AD) were probably the first to melt the raw material for brass coins using a mixture of copper and zinc ore without being aware of it. It was not until 1374 that the Indians realized that zinc was a "new" metal. In ancient Hindu writings from this time

Mining: The process of taking out minerals buried under the rocks is called mining. There are two main methods of mining, viz. open-cast mining and shaft mining. Open Cast Mining: When minerals are taken out by removing the surface layer, the process is called open-cast mining. Minerals which lie at shallow depths are extracted by this process.
