摘要
针对矿石风化严重、具有多孔状结构的细粒自然金的特点,采用氰化浸出工艺回收金.用石灰作为保护碱,氰化钠作为浸出剂,通过优化工艺条件,在原矿金品位为4.45 g/t时,可获得金浸出率为97.30%的指标.
Due to porous structure and fine gold particles in the high weathering ore, this paper presented a meth- od of leaching by cyanidation of gold with lime and sodium cyanide. Under optimized conditions, a good technical index of Au recovery by cyanide leaching 97.30% was obtained when the Au in the crude ore was 4.45g/t.
