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.
