摘要: 针对龙桥铁矿铜硫混合精矿的特点,通过对其进行再磨,磨矿细度-45μm占88.00%,经过一次粗选,一次精选和一次扫选的选别流程,使铜、硫精矿品位和回收率分别达到了20.84%、90.54%和49.48%、94.85%的较好指标,有效地解决了混合精矿中铜硫分离困难的问题。

Abstract: In light of the features of bulk copper-sulfur concentrate of Longqiao Iron Mine, the bulk concentrated was reground to 88.00% -45 μm  and then treated by one roughing, one cleaning and one scavenging flowsheet. As a result, the grade and recovery of the copper concentrate and the sulfur concentrate reached 20.84% and 90.54 %, and 49.48% and 94.85% respectively, rather good metallurgical performance. Thus, the difficulty in separating the copper from sulfur in bulk concentrate was effectively solved.
