The mining industry is an important industry in South Africa. It involves a number of industries working together. Exploration is followed by excavation, which is followed by crushing and milling to reduce the size of the rocks. This is followed by extraction (removing the valuable minerals from the ore) and finally refining.

A common method to mill the crushed rock is milling in large rotating drums with metal balls, grinding the rock to small particles and liberating ore and gangue minerals from each other. Milling is one of the most energy intensive steps in mining, accounting for most of the energy consumption at a mine. Separation and concentration

The breakage and liberation of minerals are the key to fluidized mining for minerals. In the ball milling process, steel balls function as not only a grinding action implementer but also energy carrier to determine the breakage behavior of ores and the production capacity of the mill. When ground products present a much coarse or much fine particle size distribution, the separation process ...
