How is Gold mined? Complete Mining Process

Placer gold mining involves using mercury to form mercury-gold amalgam having small gold elements. Mercury process is sopped in large-scale mining processes, but it is used in small-scale mining processes. Recent studies estimated that, in California, 45000 metric tons of mercury are used for placer mining. Where Is Gold Found? The process of gold mining occurs in different countries such as the
