apatite mineral processing

Flotation study of fine grained carbonaceous sedimentary apatite ore

All minerals, apatite (Ca 10 (PO 4) 6 F 2), dolomite (CaMg(CO 3) 2) and calcite (CaCO 3) belong to the group of semi-soluble salt-type minerals with similar cations (Ca 2+) (Komar Kawatra and Carlson, 2014). Apatite, dolomite and calcite minerals are sparingly soluble and will release their lattice constituents into the solution.
