Dolomite Beneficiation And Uses

Beneficiation of dolomites SpringerLink

We established the possibility of greatly improving the quality of ordinary dolomites by removing from them large lump ballast impurities by separation in heavy suspensions and using photoelectronic sorting techniques.The introduction of these methods of mechanical beneficiation for dolomites will exclude manual sorting of the rocks used in certain enterprises which now

"BENEFICIATION OF HIGH-MgO SEDIMENTARY

Dolomite [CaMg(CO3)2] is an intolerable impurity in phosphate ores due to its MgO content. Traditionally, the Florida phosphate industry has avoided mining high-MgO phosphate reserves due to the lack of an economically viable process for removal of dolomite. However, as the high grade phosphate reserves become depleted, more emphasis is being put on the development
