Abstract:
The copper slag produced by Ausmelt Furnace contains a large scaled of valuable elements. In this paper, the copper in the slag was efficiently recovered by the process of flotation. The influences of cooling method, grinding fineness, and collector on beneficiation indexes were investigated. The structural and morphological properties of the slag were studied by SEM-EDS. And the results show that, applying the process of stage-grinding and stage-separation, simultaneously under the conditions of coarse grinding fineness at -0.074mm75%, regrinding fineness at -0.043mm85%, dosages of sodium sulphide, butyl xanthate and 2#oil for 95g/t, 90g/t, 85g/t, respectively, copper concentrate can be recovered from primary slag which includes 0.74% copper, and the grade is 16.11% with recovery of 69.90%. In addition, comprehensive utilization of the industrial electric furnace slag was studied, it indicated that the benefit of using flotation process to recover the copper from the slag is considerable.
