2021-10-15  The PGEs and gold are solubilised as chloro-complexes by the addition of chloride salt to the autoclave, while base metal sulphides are oxidised to form soluble metal sulphate complexes. The precious metals can be recovered directly from the autoclave discharge slurry by carbon absorption, or by precipitation with sulphide ions.

Method for the recovery of gold using autoclaving

An autoclave temperature of 500° F. was required in this example to obtain a gold extraction in excess of 90 percent. A soda ash concentration equivalent to 100 pounds per ton of ore solids yielded slightly higher gold recoveries than did a soda ash concentration equivalent to 50 pounds per ton of ore solids.
