Flotation separation of carbonate from sulfide minerals, I ...

01.07.2004· This is usually achieved by direct flotation of the gold and sulfide minerals into a bulk flotation concentrate. However, if the flotation recoveries of gold and sulfide are unsatisfactory, reverse flotation of the carbonate minerals is a possible alternative. In this study, calcite and dolomite were used as representative carbonate minerals, and pyrite and chalcopyrite as representative sulfide minerals to study the feasibility of the reverse flotation…

BENEFICIATION OF DOLOMITE AND MAGNESITE

dolomite were liberated at 100 mesh size. Flotation tests conducted under the optimum con-ditions of 80%--200 mesh feed, 0.68 Kg/tonne of sod. silicate, and 0.44 kg/tonne of sod. oleate yielded a concentrate assaying 2.7% insol. After one cleaning, the product analysed 30.4% CaO and 21.25% MgO with 1.75% insol. Cationic flotation tests using amine
