Abstract
A number of different chemical substances were evaluated for their abi lity to depress dolomite in the flotation of apatite and collophane fr om dolomite. Carboxymethyl cellulose was found to be the best depressa nt and citric acid and naphthyl anthyl sulfonates were found to be goo d depressants for dolomite. None of these substances significantly dep ressed apatite or cellophane. EDTA was found to be a dolomite activato r rather than depressant. The other chemicals studied had little effec t on either dolomite or apatite flotation. (C) 1997 Published by Elsev ier Science Ltd.
