摘　　要：某黄金冶炼公司高硫金精矿浸出给矿细度-37μm占93%,氰渣金品位1.30 g/t。为进一步降低氰渣金品位,在前期艾砂磨机半工业试验验证成功基础上,在生产现场安装ALC-3900L型艾砂磨机,对高硫金精矿进行再磨浸出。工业应用结果表明:细度-37μm占比由92.42%提升至98.80%,细度-20μm占比由70.56%提升至89.29%;氰渣金品位从1.30 g/t降低至1.08 g/t,经济效益显著。The fineness of the high sulfur gold concentrate leached from a certain gold smelting company is-37μm,accounting for 93%.After leaching,the cyanide residue gold level is around 1.30 g/t.In order to further reduce the gold grade of cyanide residue,ALC-3900L ALC mill was installed on the production site to regrind the high sulfur gold concentrate based on the successful pilot test of ALC mill in the early stage.The industrial application results show that after the ALC mill is applied to the regrinding of high sulfur gold concentrate,the fineness of-37μm increases from 92.42%to 98.80%,and the fineness of-20μm increases from 70.56%to 89.29%;After leaching high sulfur gold concentrate,the cyanide residue gold level decreased from 1.30 g/t to 1.08 g/t,indicating significant economic benefits.
