Beneficiation of dolomites SpringerLink

The introduction of these methods of mechanical beneficiation for dolomites will exclude manual sorting of the rocks used in certain enterprises which now produce dolomite. Dolomites distinguished by fine accumulations of impurities can be successfully treated by flotation to obtain high quality concentrates, the content of harmful impurities ...

Beneficiation of Dolomitic Idaho Phosphate Rock by the

Bench scale beneficiation studies were made on Idaho dolomitic phosphate rock using the TVA carbonate flotation process. The process used diphosphonic acid as a phosphate mineral depressant and fatty acid as a carbonate mineral collector. Silica was subsequently rejected as float using an amine collector, with phosphate product recovered as the sink fraction. Two samples of prepared flotation ...
