Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in several processing industries. Historically this was first used in the mining industry. William Haynes in 1869 patented a process for separating sulfide and gangue minerals using oil and called it bulkoil flotation.

During froth flotation the ore is crushed and ground to a specific size sufficient for mineral liberation. The ore is then suspended in slurry and mixed with reagent or collectors. The collectors react with sulphide mineral particles to make them hydrophobic. The treated ore is introduced to a water

The grinding environment had lesser effect on the resulting froth stability, although mild steel grinding gave higher froth stability compared to stainless steel grinding. The experimental evidence supports the hypothesis that in porphyry copper flotation the grinding environment influences surfaces oxidation, pyrite activation and the extent of hydrophobic particles reporting to the froth phase.

AbstractFroth flotation is widely used for concentration of base metal sulphide minerals in complex ores. One of the major challenges faced by flotation of these ores is the ever varying grade and mineralogy. This therefore calls for a continual characterisation and optimisation of flotation parameters such that concentrator performance as a
