Flash flotation and the plight of the coarse particle

2012-7-1  Adjustment of flotation conditions, such as reagent addition rate and pH have a much greater impact on coarse particle flotation than any other size range (Trahar, 1981) and specialty reagents are often required to extend the upper size limit of flotation (Yoon et al., 2002).An example which highlights the impact of pH on the coarse fractions is given by Senior et al. (1994), who studied the

Mineral processing metallurgy Britannica

2021-6-3  Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.The primary operations are comminution and concentration, but there are other important operations
