摘要
辽宁某金矿矿石,属于低硫含金石英脉矿石。金矿物有自然金、银金矿和金银矿三种。通过试验研究,采用磨矿细度为-0.075mm 65%,pH=7.5,异戊基黄药60g.t-1的工艺条件和药剂制度,获得了精矿含金品位264.52g.t-1,回收率94.61%的较好工艺指标。
A gold mine ore in Liaoning belongs to the low sulfur auriferous quartz vein ore. Gold minerals are native gold , electrum and kustelite ore . Under the process conditions and reagent regime of grinding fineness -0.075 mm 65%,pH = 7.5,isoamyl xanthate 60 g·t^-1,experimental study gained the better process indicators of concentrate gold grade 264.52 g·t^-1, recoveries 94.61%.
