摘要: 铜绿山铜铁矿针对因硫化矿矿石性质变化而引起的铜回收率下降问题,进行了采用MB和MOS-2混合捕收剂替代异丁基黄药的实验室试验,并在此基础上进行了工业试验。工业试验结果表明,与异丁基黄药相比,MB与MOS-2混合捕收剂可使铜精矿铜、金及银的回收率分别提高0.49,3.62和3.47个百分点,同时可降低2号油用量40%以上。按此推算,采用MB与MOS-2混合捕收剂选别铜绿山硫化矿,每年可为企业增加经济效益165.06万元。

Abstract: The property change of the sulfide ore of Tonglushan Copper-Iron Mine led to the decline in copper recovery. Laboratory test was made on using MB and MOS-2 collector combination instead of sodium isobutyl xanthate. The following industrial test indicated the MB and MOS-2 collector combination can raise the copper, gold and silver recoveries of copper concentrate by 0.49,3.62 and 3.47 percentage points respectively, and meanwhile, reduce the No. 2 oil consumption by more than 40%. In this way, the adoption of this collector combination for the sulfide ore of this mine can bring an economic benefit of 1.6506 million yuan per annum.
