Case Studies Mineral Processing Gold Leaching Gold Cyanidation Ground Truth Trekking

Cyanide and oxygen are required to dissolve microscopic gold particles from finely ground ore at the gold mill A slurry containing 50 by weight ore flows continuously through a series of large tanks to extract the precious metalCyanide vat leaching mixes finely crushed ore with a cyanide salt in water The cyanide binds to the gold ions and makes them soluble in water thereby allowing separation from the rock This process usually takes place inside a mill or other mining facility
