  • How is gold found and extracted from mines?

    Water is then added to the powder to produce a pulp, which is run through a series of leaching tanks. Using a chemical solvent, usually cyanide combined with oxygen, the gold is extracted from the pulp inside these tanks; but it is still not pure gold. This process is known as carbon-in-pulp. The result is gold that is attached to carbon.
