摘要
采用新型浮选药剂对河南某低品位难选钼多金属矿开展了铜钼混合浮选-铜钼分离试验研究。结果表明,铜钼混合浮选以L43为捕收剂、L56为起泡剂,铜钼分离以L789为铜硫抑制剂,采用二粗一精二扫铜钼混合浮选-铜钼混合精矿再磨-一粗三精三扫铜钼分离试验流程,获得了Mo品位50.780%、Mo回收率65.30%、Cu品位0.602%、Cu回收率4.72%的钼精矿和Cu品位0.165%、Cu回收率4.49%、Mo品位0.362%、Mo回收率1.61%的铜精矿,混合尾矿中铜回收率达到了90.79%。
An experimental study with a novel flotation reagent was carried out for some refractory low-grade polymetallic ore from Henan Province,and a process of Cu-Mo bulk flotation,followed by Cu/Mo separation was adopted in the experiment.With a processing flow consisting of a Cu-Mo bulk flotation(including two stages of roughing,one stage of cleaning,and two stages of scavenging)with L43 as a collector and L56 as a frother,followed by regrinding of the obtained Cu-Mo bulk concentrate,and Cu/Mo separation(including one stage of roughing,three stages of cleaning and three stages of scavenging)with L789 as a depressant,the experiment produced a molybdenum concentrate grading 50.780%Mo,0.602%Cu with 65.30%Mo recovery and 4.72%Cu recovery,and a copper concentrate grading 0.165%Cu and 0.362%Mo with recoveries of 4.49%Cu and 1.61%Mo.It is shown 90.79%Cu is recovered into the mixed tailings.
