Phosphorite, phosphate rock or rock phosphate is a non-detrital sedimentary rock that contains high amounts of phosphate minerals.The phosphate content of phosphorite (or grade of phosphate rock) varies greatly, from 4% to 20% phosphorus pentoxide (P 2 O 5).Marketed phosphate …

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 …

A large variety of techniques and types of equipment are used to extract phosphate ore which is in the form of layers. After stripping the overburden, the phosphate ore is stripped by dozers and transported by tracks, belts or water carrying to the beneficiation area. Apatite is the main mineral of phosphate ore.
