摘要

This complex Cu-Pb-Co-Ni multi-metal sulfide ore in Australia has a fine dissemination size, andthere is a very close symbiotic relationship among sulfide minerals, and between sulfide mineralsand gangues, which makes beneficiation difficult. And high content of carbon is also a difficulty formineral processing. Based on research of process mineralogy, a new process flow of ‘C flotation – Cu-Pb-Co bulk flotation –Co flotation for tailing, cleaning for concentrate – regrinding – C 2nd flotation– Cu, Pb, Co separation’ is determined. The lock-cycled test achieved test indexes as following:Pb concentrate: Pb grade 55.50 per cent, Pb recovery 56.92 per cent, Co-bearing 0.58 per cent, Corecovery 22.04 per cent, Cu-bearing 3.76 per cent;Cu-Co bulk concentrate: Cu grade 6.41 per cent, Cu recovery 50.77 per cent, Co grade 0.94 per cent,Co recovery 40.95 per cent, Pb-bearing 12.91 per cent, Pb recovery 15.24 per cent;Co concentrate: Co grade 0.35 per cent, Co recovery 14.00 per cent, Cu-bearing 1.29 per cent, Pbbearing8.90 per cent;Above results indicate that the process flow used in this paper is suitable for this complex multimetalsulfide ore in Australia because Cu, Co, Pb especially Co can be recovered effectively, and it isalso a harmonious technology method for this ore.
