抄録

An aqueous pulp of the complex sulphide concentrates (-200mesh) having a content of 10.6 pct Cu, 20.5 pct Zn, 20.9 pct Fe and 34.7 pct S was treated with oxygen at elevated temperatures and pressures.<BR>99 pct of zinc and 95 pct of copper in concentrates were extracted under the following conditions. pulp density; 10.7 pct solid leaching time: 1 hr temperature: 185°C total pressure: 40 atm.<BR>99 pct of zinc and 90 pct of copper were leached at 170°C, under 20 atm in 4 hrs.<BR>At a temperature of 185°C and a total pressure of 40 atm, pulp density and leaching time were varied as follows: pulp density: 10.7 to 24.2 pct solid (30 to 80 g in 250 cc water) leaching time: 1 to 5 hrs.<BR>More than 95 pct of zinc in concentrates were always leached under these conditions, and 90 pct of copper were extracted when the pulp density is 24.2 pct solid and reaction time is 4 hrs.<BR>The more the amount of iron were leached, the higher the pulp density became, but these were not affected by the leaching time.
