The beneficiation of high talc-containing copper–cobalt flotation tailings was studied by centrifugal gravity concentration. It was found that copper and cobalt minerals were finely disseminated in the gangue matrix so that conventional gravity concentration using spirals and shaking tables would be ineffective.

Microbially induced mineral beneficiation involves three strategies, namely, selective bioleaching of the undesirable mineral from an ore or concentrate, selective flotation of the mineral, or selective dispersion/flocculation. Such microbially induced beneficiation will find applications in a number of areas such as: Desulfurization of coals ...

11.5.3.1 Beneficiation. Mineral beneficiation begins with crushing and grinding of mined ore for near-complete separation of ore and gangue minerals as well as between ore minerals. Each processing step is designed to increase the grade (concentration) of the valuable components of the original ore.

The dominant challenge of current copper beneficiation plants is the low recoverability of oxide copper-bearing minerals associated with sulfide type ones. Furthermore, applying commonly used conventional methodologies does not allow the interactional effects of critical parameters in the flotation processes to be investigated, …

In this study, an attempt was made to recover copper from AbuSwayel deposit. A reverse flotation technique was applied leading to flotation of the accompanying oxide and sulfide minerals and gath ering copper oxide minerals in the sink product. The results showed that the application of such tech nique is possible under the optimum flotation conditions. …
