磨矿细度对富叙漫出的影晌
磨矿细度氰化试验条件:矿浆浓度33%,pH1.05~11,氰化液浓度,0.4g/L,氰化时间42h,氰化钠用量1~1.5kg/t,调碱度用氧化钙,用量为2kg/t,
随着磨矿细度增加,浸渣品位下降,金的浸出率提高。但-74μm粒级达到65%后,变化已不显著。因此,磨矿细度以-74μm占65%为宜。

Grinding fineness cyanidation test conditions: slurry concentration of 33%. PH1.05 ~ 11, cyanide concentration, 0.4g/l, cyanide time 42h, dosage of sodium cyanide 1 ~ 1.5kg/t, alkalinity with calcium oxide, dosage for 2kg/t,

With the increase of grinding fineness, the grade of leaching slag decreased, and the leaching rate of gold increased. But after 74 m grain level reached 65%, the change was not significant. Therefore, the fineness of grinding - 74 m accounted for 65% of the appropriate.
