How Is Gold Purified Sciencing

· For high grade ore the metal is sent to a grinding mill and made into a powder Refractory ore contains carbon and is heated to over 1000 degrees F which removes sulfide and carbon The resulting oxide ore is directed to the leaching circuit Sulfide refractory ore that contains no carbon is oxidized in an autoclave to free gold from sulfide minerals then it is sent to the leaching circuit
