ABSTRACT:
A process for the recovery of gold from refractory auriferous iron-containing sulphidic material which comprises providing an aqueous feed slurry of fresh feed material and oxidized solids from a subsequent pressure oxidation step. The feed slurry has a pulp density in the range of from about 30 to about 60% by weight. The slurry is subjected to pressure oxidation at a temperature of from about 120.degree. to about 250.degree. C. under a total pressure of from about 360 to about 6000 kPa to produce a slurry of oxidized solids. A portion of the oxidized solids is recycled to the feed slurry, and gold is recovered from the remaining oxidized solids.
