Haldar ( 2013) described mineral processing «as the value-added processing of raw material (run-of-mine ore) to yield marketable intermediate products (e.g. copper concentrate) or finished products (e.g. silica sand) containing more than one valuable minerals and separation of gangue (tailing).».

The aim of a mineral processing operation is to concentrate a raw ore for the subsequent mineral extraction stage. Usually, the valuable minerals are first liberated from the ore matrix by comminution and size separation processes (crushing, grinding, and size classification) and then separated from the gangue using processes capable of …

The mineral is usually transferred to the froth leaving behind the gangue in the pulp. This is termed as direct flotation. However, during reverse flotation the gangue is separated into the float fraction while the valuable mineral is retained in the pulp. The process can only be applied to relatively fine particles.

2.1 Energy. Rock drilling, blasting, and comminution (crushing and grinding) consume a vast amount of energy in hard rock mines. As mentioned in Sect. 1, statistics from hard rock mines indicates that drilling and blasting consumes 2% and comminution does 53% of the total energy input in the whole production chain from mining to mineral …

Bond's work index model of quantifying mineral grindability was born out of the desire for a better way of scaling up laboratory grindability test results to industrial-scale grinding mills (Lynch & Rowland, 2005). The Allis-Chalmers company (now ) collected a great deal of operating and laboratory data during the 1930s
