Ores of the aforegoing minerals which contain substantial amounts of talc had heretofore been particularly resistant to economic treatment through flotation as the finely divided talcose materials have interfered with the differential activation and flotation of the minerals.

Micro-Flotation Experiments With The Blasted And Un-Blasted Talc Particles Many papers in the literature have been dedicated to the effect of morphological parameters in particular those on talc flotation (Kursun et al., 2022, Ulusoy et al., 2022).

for sulphide flotation (Cao and Liu, 2022), but the presence of chlorite and talc, which have a natural floatability, lowers the grade of the lead concentrate. An additional 'mica' flotation circuit, upstream of the lead flotation circuit, is used from time to time to reduce the content of these silicate minerals in the feed to lead flotation.
