Abstract

In this paper a experimental research on beneficiation technology for a sulfur-bearing bulk copper in Yunnan. Ore slime content is higher in the ore ,chalcopyrite is closely associate with pyrite ,the raw ore grading 0.95%Cu and 17.88% S .The flow sheet of raw ore-washing, stage-grinding, stage-concentration, copper-sulfur bulk flotation were adopted in the test. copper-sulfur bulk flotation while the ore was grind to fineness of -0.074mm 60%,the obtained concentrate been cleaning again was regrinding to a fineness of -0.074mm 90% for copper-sulfur separation. The study examined the effect of reagent rate by flotation technique using sodium sulfide 500g/t, butyl xanthate : ammonium butyl (4:1) 60g/t, terpenic oil 20g/t, lime 2000g/t. The copper concentrate with grade of 16.12% and recovery rate 90.13%,the sulfur concentrate with grade of 32.21% and recovery rate 70.72%.It has some direction significance to the same sulfur-bearing bulk copper beneficiation.
