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 DOLOMITE AND MAGNESITE

2011-8-9  BENEFICIATION OF DOLOMITE AND MAGNESITE DOLOMITE D OLOMITE is important raw material for the refractory industry and also for the extraction of magnesium metal. Silica is the normal gangue mineral and is separated by froth flotation only. Only one sample was tested for beneficiation. The sample was received from M/s. TISCO Ltd.

Beneficiation of Florida Dolomite Phosphate Ores

1984-2-1  The Bureau of Mines, US Department of the Interior, conducted studies to recover phosphate from four dolomitic southern Florida deposits not currently mined. The samples contained 5.8–10.2% P2O5 and 1.7–4.8% MgO. Chemical analyses of sized fractions indicated that no pebble concentrate, +1.2 mm (+ 14 mesh) could be produced from these samples. A scheme was developed that

Beneficiation of phosphate ores by electrostatic processes has been demonstrated by various researchers since the 1940’s. Separations have been achieved by removing silica from phosphates, and with fewer examples of calcite and dolomite from phosphate. Limitations on conventional electrostatic systems include low capacity, the need for multiple stages, and operational problems caused by fines.
