摘　　要：安徽某铜硫矿现场选矿工艺为"铜硫等可浮出快铜-中矿再磨-铜硫分离",得到的硫精矿产品品位不够理想,仅为41.43%,离要求的48%差距较大。针对这一情况,本文开展了选矿工艺试验研究,针对含Cu 0.85%、S 15.23%的原矿,采用"铜硫混浮粗精矿再磨脱脉石-铜硫分离"工艺流程,闭路试验最终获得铜精矿含Cu 17.41%、S 32.44%,Cu回收率86.46%;硫精矿含Cu 0.24%、S 48.95%、Fe 44.01%,S回收率60.78%。A technology of ’copper-sulfur iso-flotation-middling regrinding-copper-sulphur separation was used in a copper-sulfur ore plant in Anhui province.The S grade of sulphur concentrate is not ideal,only 41.43%,quite different from the requirement of 48%.In view of this situation,the optimization experiments of ore dressing process were carried out in this paper.For run-of-mine containing Cu0.85%,S 15.23%,a copper concentrate contains Cu17.41%,S 32.44%,Cu recovery of 86.46% and a sulfur concentrate contains Cu 0.24%,S 48.95%,Fe 44.01%,S recovery of 60.78% were achieved in closed-circuit test by using the technology of "copper-sulphur bulk flotation-rough concentrate regrinding-gangue removal-copper-sulphur separation".In the case of the copper index,the quality of sulfur concentrate has been improved significantly,and the technology support is provided for tapping the potentials of the plant.
