Extracting gold from rock OpenLearn Open University

So how do you use mercury to extract the gold from goldbearing rock? When you mix the finely powdered goldbearing rock with some mercury, the gold within the rock dissolves, to form what''s called a gold amalgam. The next step in the process is to separate the gold amalgam from any ''unreacted'' mercury.

History Of Mercury Use in Products and Processes Mercury

History Of Mercury Use in Products and Processes Mercury

By 1000 CE, mercury was used to extract gold by amalgamation. The mercury surrounds the gold, forming shiny pellets that workers then burn. The mercury evaporates, leaving the purified gold. This process is still practiced by artisanal smallscale gold mining operations today, exposing over 10 million of workers to the toxic element and
