对难处理金精矿进行了超细磨—氰化浸金的试验研究。最优工艺条件为：磨矿介质粒径1．6 mm、磨矿时间45 min、氰化浸出矿浆浓度33．33％、氰化钠质量分数0．5％、搅拌浸出48 h。在此试验条件下，金浸出率可达93．70％。
@@@@This study is concerned on ultra-fine grinding-cyanide leaching process for refractory gold concen-trates.The optimal conditions are like this:grinding media size 1.6 mm,grinding time 45 min,cyanide leaching pulp density 33.33 %,cyanide concentration 0.5%and leaching time 48 h.Under such conditions,the gold leaching rate reached 93.70 %.
