Abstract:
     This process includes supplying the fresh feed material and aqueous feed pulp of oxidized solid from the follow-up pressure-oxidization process. The consistency of the feed pulp is 30-60% by weight. The pulp is pressure-oxidized under the temp. of 120-150 deg.C and the pressure of 360-6000 kpa to produce the oxidized solid pulp. One part of the oxidized solid is fed back to the feed pulp for recycling and the gold is recovered from the rest part.
