How Is Gold Processed? |
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.

Gold extraction Wikipedia
A "refractory" gold ore is an ore that has ultra fine gold particles disseminated throughout its gold occluded minerals. These ores are naturally resistant to recovery by standard cyanidation and carbon adsorption processes. These refractory ores require pretreatment in order for cyanidation to be effective in recovery of the gold.
