The iron ore industries of India are expected to bring new technologies to cater to the need of the tremendous increase in demand for quality ores for steel making. With the high-grade ores depleting very fast, the focus is on the beneficiation of low-grade resources. However, most of these ores do not respond well to the conventional …

Flotation is the preferred concentration technique because talc is naturally floatable, requiring only a frother to affect flotation [3-71. In the current study, a representative sample of Egyptian talc-carbonate ore was subjected to beneficiation to obtain a clean talc product suitable for industrial uses.

ABSTRACT 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. The actual …

Natural concentrations of ore minerals form discrete ore bodies that may typically contain only a few percent of the valuable metal. Unlike many industrial minerals that find direct use after mining and limited beneficiation, the ore minerals, in general, must be reduced to metal by complex processing. Modern mining and mineral extraction ...

Talc is an industrial mineral, which is composed of hydrated magnesium sheet-silicates with theoretical formula of Mg3Si4O10(OH)2 that belongs to the phyllosilicate family (Fuerstenau and Huang, 2003; Ozkan, 2003; Yehia and AL-Wakeel, 2000; Boghdady et al, 2005). Talc may have white, apple green, dark green or brown colors, depending on its composition.
