The effect of grinding environment on flotation of
2010-10-1 · Grinding is the most dominant variable influencing the flotation since in addition to size reduction it determines the potential and pulp chemistry under which the ore is conditioned. For example different gases have been reported to influence pulp potential and therefore flotation selectivity of a complex Cu/Zn ore . Conventional grinding acts as a pre-treatment step for flotation since it produces

The ball mill is the fine grinding machine connect the SAG or AG mill and flotation machine. Ball mills produce fine particles with a uniform size for flotation its grinding medias commonly are steel ball. The ball mill rolls grinding media together with the ore as the ore grinds these balls initially 5-10 cm in diameter but gradually wear out.
