There are many steps to this kind of mining; here are some of the steps: Ore extraction. Basically, "ore extraction" means digging. Digging for A LOT of solid rock out of mountains. The way you get to that rock is by digging hallways to the rocks that have the most gold in them. Those hallways are called 'tunnels' and 'mine shafts'.

2020-3-29 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.
