challenges in cocrusher flotation of chalcopyrite

Little abrasion wear, Long service life

Based on 30 years of development experience of grinding equipment, LM Heavy Industry produced LUM Series Superfine Vertical Roller Grinding Mill to make ultra-fine powder. The grinding roller doesn't contact with millstone usually, which makes abrasion little and service life longer.

Applications: Superfine dry powder of none-metal ores such as calcite, marble, limestone, coarse whiting, talc, barite and dolomite and so on.

cocrusher flotation parameters of chalcocite ore

2. Flotation of middling particles (i.e. higher than 200 µm) improves with increased pH. This is true in the case when chalcocite is the major copper mineral. In the case of chalcopyrite ore, a lower pH is more desirable (i.e. 8.5–9.5) because at a higher pH, the flotation of chalcopyrite is decreased, especially for the coarser particles.
