Abstract. The flotation process currently considered for apatite concentration from the Santa Quit ria phosphate deposit Brazil involves bulk flotation of apatite and calcite with anionic collector at pH10 followed by calcite flotation at pH5.5 adjusted with H 3 PO 4.Although this concept is efficient from the point of view of separation between apatite and calcite the intensive use of .

May 05 2017 The calcium ion dissolved from calcite mineral surfaces which exist in the coal sources provided an explanation for the depression of monazite in the combined systems. Single mineral flotation of monazite and calcite showed that sodium silicate and sodium hexametaphosphate efficiently depressed calcite while providing minimal effects on .

Phosphate Rock Treatment for Waste Reduction

Phosphate Rock Treatment for Waste Reduction

Separation of calcite andor dolomite from phosphate rock by flotation is becoming the practice in several phosphate mining areas where higher carbonate contamination is encountered. In almost all cases the phosphate rock must be ground to liberate the calcite andor dolomite so that it can be separated from the phosphate rock.

Flotation of phosphate Phosphate ore is the most important source of phosphorus in fertilizers. To supply the phosphoric acid plant with phosphate a high grade of phosphorus is essential as well as reduced levels of impurities such as magnesium iron and aluminum oxides. Flotation is one of the key beneficiation methods.
