Surface Electrical Behaviors of Apatite, Dolomite, Quartz

In the real phosphate ore flotation process, different ions in the pulp change the surface electrical behavior of minerals and hence change the selective adsorption of beneficiation reagent on the mineral surface, which enlarges the difficulties in the selective separation of apatite from dolomite and quartz (Amankonah et al., 1985).

Dolomite, for example, is composed of calcium carbonate and magnesium carbonate minerals, these can be separated mechanically. Although this material participates in the glaze melt to source the MgO and CaO (which are oxides ), it's mineralogy (the calcium and magnesium carbonates) specifically accounts for the unique way it decomposes and melts.

Optical sorter for absolutely pure industrial minerals

This extremely strong magnetic field enables industrial minerals such as limestone or kaolin to be upgraded further. For the smaller grain sizes of up to 5 mm, the higher degree of breakdown results in higher qualities. Salts can also be upgraded or cleaned by this method, by the separation of clay-containing contaminants.
