Gold mining

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.

Facts about Gold

The process for low-grade ore is relatively simple: a cyanide solution is applied to the heap, dissolving the gold, which is then collected. High-grade ore, on the other hand, heads to the grinding mill for a more extensive process. There are several different ore types which require different processes for optimal recovery of the gold.
