Abstract
If talc ore contains a large proportion of carbonates, air separation is inadequate to obtain products suitable for high-grade applications. An extra chemical treatment, using; acids, was evaluated at laborator y level, to further increase the grade of talc concentrates. It was sh own that air floated talc, having; 10 to 20% of carbonates (magnesite, dolomite and calcite), can be improved, in terms of reflectivity, las s on ignition and iron content.
