【 摘 要 】

The technological mineralogy and benefication research of an oxy-sulfur mixed copper ore were carried out. The test contents included: grinding fineness, collector dosage for sulphur ore, activator dosage and collector dosage for oxidized ore, open circuit and closed circuit test, etc. The results showed that under the grinding fineness -0.074 mm of 70%, the copper concentrate with a yield of 5.46%, a copper grade of 18.14% and a recovery rate of 68.31% was obtained through the preferred flotation process. The process was one roughing, two cleaning and two scavenging for sulphide ore, one roughing, three cleaning and three scavenging for oxidized ore. The silver content in the copper concentrate was 438 g/t, and copper content in the tailings was 0.486%. The dosage of agent in whole process were 500 g/t lime, 1500 g/t sodium sulfide, 1500 g/t SW, 827.5 g/t isoamyl xanthate, 207.5 g/t ammonium dibutyl dithiophosphate, and 260 g/t 2# oil.
