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. …
Investigations have been carried out on the possibilities to improve talc quality by using flotation and determination of the optimum values of operating variables such as depressant dosage, frother dosage and solid concentration. Studies were focused to obtain good quality talc from mineral ore samples. Pine oil was used as frother and sodium …
