【摘要】 对氨氰法浸取含铜热压酸浸渣进行了工艺试验研究,详细地考查了各操作条件对金银浸出率的影响。在矿浆浓度40%,NaCN用量8.0kg/t,NH4HCO3用量75kg/t,氰化时间16h的条件下氰化,金、银的浸出率分别为98.3%、82.7%。更多还原

【Abstract】 The experimental reseach of gold leaching of hot-press acid leaching residues by ammmoniacal cyanide process and the effects of various operation condition on gold extraction have been investigated in this paper.The extraction of Au、Ag is 98.3%、82.7% respectively under conditions that granularity of concentration of mine slurry is 20%,the NaCN and NH4HCO3 is 8kg/t and 75kg/t respectively,and ammoniacal cyanide treatment time as long as 16h.更多还原
