| Abstract: |
| In this paper，a experimental research on beneficiation technology for a slime-bearing abundant sulfur bulk copper. Ore slime content is higher in the ore ,chalcopyrite is closely associate with pyrite ,the raw ore grading 0.99%Cu and 18.32%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 56%,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 400g/t, butyl xanthate : ammonium butyl (4:1) 80g/t, terpineol oil 35g/t, lime 1500g/t. The copper concentrate with grade of 15.95% and recovery rate 88.23%,the sulfur concentrate with grade of 32.13% and recovery rate 69.84%.It has some direction significance to the same sulfur-bearing bulk copper beneficiation. |
