Hard Rock Mining Gold and Silver Ore and processing it
In most gold ores, the final process to extract the tiniest gold particles is the use of cyanide to dissolve the gold. Cyanide, in the presence of oxygen actually dissolves both gold and silver. It is both efficient and inexpensive, so it is widely used in precious metal ore processing.

When you mix the finely powdered gold-bearing rock with some mercury, the gold within the rock dissolves, to form whats called a gold amalgam. The next step in the process is to separate the gold amalgam from any unreacted mercury. We did this by squeezing the crude amalgam through a small piece of chamois leather.

In days gone by, miners and prospectors did this with hammers and a mortar and pestle, but modern gold processors use large machines called crushers to make the pebbles.
Gold mining - Wikipedia
The gold can be removed from the carbon by using a strong solution of caustic soda and cyanide, a process known as elution. Gold is then plated out onto steel wool through electrowinning. Gold specific resins can also be used in place of activated carbon, or where selective separation of gold from copper or other dissolved metals is required.
