【摘要】 针对某少硫化物微细浸染型含金矿石进行了选矿工艺研究,探索了全泥氰化、超细磨炭浸、浮选工艺选别指标。结果表明:全泥氰化、超细磨炭浸工艺金浸出率很低,最高仅为4.04%,不适宜处理该矿石;采用浮选工艺,在最佳试验条件下,闭路试验获得了较好指标,金精矿金品位27.35 g/t、金回收率90.63%。研究结果可为该类型矿石工艺流程选择提供参考借鉴。更多还原

【Abstract】 Experimental study on the beneficiation of a microfine disseminated gold-bearing ore with little sulfide was carried out, and all-sliming cyanidation, ultrafine grinding CIL and flotation indexes were explored.The results show that all-sliming cyanidation and ultrafine grinding CIL processes have very low gold leaching rates, 4.04 % at most, so they are not suitable for treating the ore; under optimal experimental conditions, the closed-circuit test of flotation obtains good index: the gold grade of gold concentrates is 27.35 g/t, gold recovery rate is 90.63 %.The study provides reference for choosing process flowsheets for the type of ores.更多还原
