Macathur And Forrester 1887 Cyanidation

Gold cyanidation (also known as the cyanide process or the MacArthur-Forrest Process) is a metallurgical technique for extracting gold from low-grade ore by converting the gold to water soluble aurocyanide metallic complex ions. It is the most commonly used process for gold extraction.Due to the highly poisonous nature of cyanide, the process is highly controversial.
