Gold processing, preparation of the ore for use in various products. Native gold is the most common mineral of gold, accounting for about 80 percent of the metal in the Earth's crust. It occasionally is found as nuggets as large as 12 millimetres (0.5 inch) in diameter, and on rare occasions ...

Gold is processed by cyanide milling, a chemical procedure that separates 95 to 98 percent of the gold from raw mined ore. It is then refined to the gold standard purity, according to Mineweb. Heap leaching is a less expensive method of gold extraction, but it is a longer process and it recovers less gold than the cyanide milling process.

In panning large samples, only one or two specks of gold could be seen, although the ore contained from 1 to 2 ounces per ton. This ore yielded only about 40 per cent, on being amalgamated, but over 90 per cent, was dissolved out by leaching the raw ore with cyanide of potassium, and similar results were obtained by chlorination.
