T-2K捕收剂优先浮选硫化铜矿石的研究

Study on Preferential Flotation of Copper Sulfide Ore With T-2K Collectors

根据Pearson硬软酸碱理论和前线轨道的研究 ,设计了一种高捕收能力、高选择性的T - 2K捕收剂。经工业试验表明 ,与黄药混浮 -分选工艺相比较 ,T - 2K捕收剂优先浮选硫化铜矿 ,铜精矿品位提高了 0 5 6个百分点 ,铜回收率提高了 2 3 1个百分点 ,铜精矿中金、铜回收率也分别提高 7 0 3个百分点和 9

Based on the study of Pearson's theory of hard-soft acids and bases and frontier molecule orbit (FMO), T-2K collector having high collecting ability and high sellectivity was designed. Industrial tests show that, compared to bulk flotation by xanthate followed by separation, the preferential flotation of sulfide copper using T-2K collector can improve the copper concentrate grade and recovery by 0.56 percent point and 2.31 percent points, gold and silver recoveries in copper concentrate by 7.03 percent points and 9.48 percent points respectively.
