Abstract
In light of the characteristics of a sulfide - oxidized copper ore in Inner Mongolia, such as high oxidation rate, high alkali gangue, and high content of slime, a systematic study was made for the ore on controlling mud, strengthening activation and collecting. Under the combined action of the ammonium sulfate, sodium sulfide and the action of strengthening collecting, when the percentage of the grinding particle less than 0.074 mm was over 85% , copper concentrate of Cu 20. 65% with a recovery of 85.49% was obtained through the closed circuit process of once roughing, three times scavenging, twain cleaning and middlings returned in order.关键词
