Abstract

In this paper, the beneficiation of a copper oxide ore of Yunnan was investigated through bench-scale froth flotation tests. During the froth flotation, the conditions that effect on the flotation performance was researched, including the grinding fineness and the dosage of lime as depressant, sodium sulphide as regulator, sodium n-butylxanthate as collector and terpenic oil as frother. Via a serious of tests, the tests conditions are determined that grinding fineness is 70%, the dosage of lime, sodium sulfide, butyl xanthate and terpenic oil was 1000g/t, 1000g/t, 150g/t and 30g/t, respectively. Finally, through the tests of close circuit of “two roughing, two concentrations and one scavenging”, a copper concentrate assaying 20.20% Cu can be obtained with the recovery of 68.11%.
