Ultimate Guide for Gold Cyanidation Process

Ultimate Guide for Gold Cyanidation Process

Gold cyanidation process can be divided into agitating cyanidation process and leaching cyanidation process. Agitating cyanidation process is applied to treating the tailings after gravity separation, amalgamative tailings and flotation gold-bearing concentrate, or applied to full slime cyanidation.
