The term 'mineral beneficiation' is generally defined as a value adding process on minerals from extraction to refining to production of the final consumable good. The history of mineral beneficiation goes to as back as in the 10th century when minerals were discovered and were at times used as a medium of exchange before the

position that mineral beneficiation is a panacea to Africa's economic challenges. The study explored arguments by scholars and policymakers as to why African countries fail to pursue mineral beneficiation which has subsequently relegated their economies to the bottom end of economic development. The research explored how …

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 filtration process involves the separation of solid particles from a liquid by subjecting the slurry into a pressurized/vacuum chamber, which is connected to the porous medium at the rear end. The liquid penetrates through the porous medium, while solid particles are retained.
