This paper reviewed the current situation of mineral processing of oxidized copper ore and introduced the condition and some issues of some copper tailings flotation. The effect of grinding and reagent consumption on flotation is discussed in this paper. As the open circuit test of two time coarse concentrating, one scavenging and two time cleaning result indicated that a copper concentrate with a grad of 18.63% Cu concentrate and a recovery of 53.28% can be obtained under the test condition as follow: grinding fineness is 95%, 0.074mm, sodium...
