Weve analyzed the Top 50 Gold Mines to find the cost per ounce of gold by continent. The top 50 gold mines alone contain more than 33.5% of the worlds gold ounces. What is the Cost of Mining Gold?

Gold Amalgamation

By the foregoing considerations the belief is confirmed that amalgamation is a physical rather than a chemical process. The solubility of gold in mercury is almost negligible, and the diffusion of the mercury into the gold, forming a solid solution or intermetallic compound, is a rather slow process, unless the gold is very finely divided, whereas the catching of the gold by the mercury
