PUBLICATION OF THE CODES OF GOOD PRACTICE FOR THE MINERALS INDUSTRY ... "Beneficiation" The term mineral "beneficiation" entails the transformation of a mineral (or a combination of minerals) to a higher value product, which can either be consumed locally or exported. ... Through Principles;
In a general sense, Beneficiation is the initial attempt at liberating and concentrating the valuable mineral from the extracted ore. This is typically performed by employing various crushing, grinding and froth flotation techniques. The remaining material is often physically and chemically similar to the material (ore or mineral)
1 Froth Flotation – Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles …
The beneficiation strategy is aimed at providing a strategic focus for South Africa's minerals industry in terms of developing mineral value chains and facilitating the expansion of beneficiation initiatives in the country, up to the last stages of the value chain.

An important aspect of any mineral processing study is an analysis of how material is distributed whenever streams split and combine. This knowledge is necessary when a flow sheet is being designed and is also essential when making studies of operating plants.
Mineral beneficiation is the first step in extraction of metal from natural resources. With the depletion of high grade metal ores it is important to increase the metal grade of an ore by physical methods; which are termed mineral beneficiation .The objectives of mineral beneficiation are •

The hydrodynamic conditions in the cell govern the formation of flocculated foams with highly dispersed air bubbles; increase of hydraulic resistance in the slurry leads to the formation of concentrates with large P 2 O 5 contents, but at lower velocity; as the solids content of the slurry increases, the relative flotation velocity at first increases, then, in dense slurries, decreases.
