摘要: 在对印尼某氧化铜矿进行工艺矿物学特性分析的基础上,开展了硫化浮选工艺条件研究,结果表明,氧化铜、硫化铜矿物同步浮选是处理该矿石的有效途径,对铜品位为1.69%、含银64.88 g/t的原矿,采用1粗1精3扫、中矿顺序返回的闭路试验流程,可获得铜品位为18.64%、铜回收率77.98%、银品位843.00 g/t、银回收率91.86%的铜精矿。

Abstract: Based on mineralogy study on a copper oxide ore from Indonesia,research on process conditions of sulphidizing flotation has been carried out.The reseach results indicated that synchronous flotation of copper oxide and copper sulfide was a effective way to process this ore.A close circuit test showed that with a raw ore assaying copper grade of 1.69% and silver grade of 64.88 g/t, a copper concentrate assaying copper grade of 18.64%,silver grade of 843.00 g/t with coppe and silver recovery of 77.86% and 91.86% respectively ,was obtained by using flow sheet of one roughing,one cleaning and three scavenging and sequential return of middlings.

Key words: Copper oxide ore, Sulphidizing flotation, Synchronous flotation, Comprehensive utilization
