| 摘 要： | 对某金矿石进行的浮选试验研究结果表明,含金黄铁矿中泥质矿物是影响金选矿工艺指标的主要因素,在强化载金黄铁矿浮选的同时,选择合理的调整剂可以显著的提高金的选矿工艺指标。经过试验研究,在原矿含金品位为2.53g/t时,浮选获得了金精矿含金品位为62.50g/t,金回收率为92.60%的工艺指标。新型复合捕收剂sk和调整剂羧甲基纤维素的应用是提高精矿含金品位的关键。

| Abstract: | An experimental study result of a kind of gold ore shows that the main factor affecting the miner-al flotation process index is the clay mineral in gold-bearing pyrite . At the same time of strengthening flo-tation of gold loaded pyrite , choosing a reasonable adjustment can significantly increase the mineral flota-tion process index . Through experimental study , when the gold grade of a raw ore is 2 .53 g/t ,the better process indexes have gain by flotation ：the grade of gold-bearing gold concentrates is 62 .50 g/t , and the gold recovery is 92 .60% .The application of new type composite collectors sk and regulator carboxymeth-ylcellulose is the key to increase the gold concentrate grade . |
