Effect of reducing grinding conditions on the flotation ...

01.10.2012  According to Bradshaw et al. (2006) a reducing grinding environment may reduce mineral surface oxidation and may benefit flotation performance, particularly for PGM ores containing very small amounts of sulphide minerals. Reducing conditions lead to a reduction in mineral surface oxidation and reduced collector oxidation: A reducing environment lowers the

How Temperature Affect Grinding Efficiency

24.10.2017  In autogenous milling, temperature can significantly influence the grinding efficiency, particularly if the temperature falls below about 10°C. these efficiency changes can be reduced by preventing recycle water from becoming chilled, and by thawing frozen rock before grinding. Since the magnitude of the efficiency change is reduced at higher temperatures,
