- How Does Gold Extraction Work? - United States Gold Bureau Hard-rock mining which makes up the majority of today’s commercial gold sourcing requires a more in-depth chemical-reliant extraction process. The most used approach in this case is gold cyanidation which in short uses a cyanide-based solution to separate precious metals from encapsulating rock.
Gold Processing Equipment Process Flow Cases - JXSC There are amalgamation gold extraction process and cyanide process gold extraction. The amalgamation process is an old gold extraction process simple and economical suitable for the recovery of coarse-grained monomer gold but it has pollution to the environment and is was gradually replaced by gravity separation flotation and cyanidation
