This study was used to beneficiate talc- carbonate ore to obtain talc concentrates suitable for various industrial uses. Effects of pH and frother dosage on the flotation process were studied.

Ground high-grade ore with the d80 of 150 μm was subjected to a series of batch laboratory flotation tests, aimed at determining the natural flotation kinetics of talc mineral, using Methyl isobutyl carbinol (MIBC) frother as the only reagent.

Froth flotation is a surface chemistry based separation process which is extensively used in the processing of mineral ore deposits as a method of separating the desired mineral component from their associated gangue material [17,34].
