Frontiers Surface Electrical Behaviors of Apatite ...

The valuable mineral, apatite, in phosphate ore has the same lattice ion, Ca 2+, as dolomite, which results in a significant effect on the selective flotation of apatite from dolomite. 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

Mining and Beneficiation – Phosphate Research

Many impurities are inside apatite mineral, but some of them are outside the apatite mineral. The major part of exogangue impurities are composed of silicates, carbonates and clays. To concentrate phosphate rock in apatite (BPL or P2O5 content) we have to separate impurities from apatite using a beneficiation process.

Apatite: Its uses as a mineral and gemstone

What is Apatite? Apatite is the name of a group of phosphate minerals with similar chemical compositions and physical properties. They are an important constituent of phosphorite, a rock mined for its phosphorus content and used to make fertilizers, acids, and chemicals. Apatite has a relatively consistent hardness and serves as the index mineral for a hardness of five in the Mohs Hardness Scale.
