How is Silver Mined | APMEX®
Silver also occurs alongside lead, copper and zinc ores, which is why nearly 50% of mined Silver today is obtained when processing other kinds of ore. Silver is separated from this ore using a chemical process known as smelting. To begin a new Silver mine, a system of multi-layered crosscuts are made.
