2021-8-19 · AEROPHINE Ⓡ 3418A promoter has been historically known to provide good selectivity on various Cu-Ni ore bodies against pyrrhotite and MgO. Its use can reduce the quantity of xanthate required, while increasing Cu flotation kinetics and providing improved metallurgy. Additionally, it does not produce CS2 or COS, which is a significant advantage in terms of health and safety when compared …
2021-9-13 · The comminution test work included semi-autogenous grind mill comminution on the new drill core, Bond rod mill work index, Bond ball mill work index and abrasion index tests. The results indicate the material is hard with results ranging from 11.8 -24.6 kWh/t and the 75 th percentile of the samples tested was 21.1 kWh/t for the variability samples.
