The technological research on the separation between law alkalinity copper and sulfur of a certain miner containing copper sulfur iron in anhui

The research object of this paper is a certain complex sulfur-iwn which contains copper in Anhui province. It focuses on the flowsheet about the separation of copper and sulfur in low alkalinity condition. The content of copper in the original oar is 0.39%, and sulfur is 36.19 percent. In low alkalinity conditions, we used copper compound maily LP collectors, first through copper selective flotation, then through sulfur selective flotation in which the original slurry didn´t get activated. It was obtained that the grade of copper concentrate was 18.46 percent and copper recovery was 72.16 percent percent;the grade sulfur concentrate was 48.14 percent and sulfur recovery was 93.72 percent.
