Phosphorite, phosphate rock or rock phosphate is a nondetrital sedimentary rock which contains high amounts of phosphate phosphate content of phosphorite (or grade of phosphate rock) varies greatly, from 4% to 20% phosphorus pentoxide (P 2 O 5).Marketed phosphate rock is enriched ("beneficiated") to at least 28%, often more than 30% P 2 O occurs through washing, screening ...
Apatite is best known for its use as an index mineral with a hardness of 5 in the Mohs Hardness Scale. It is usually green in color, but can be yellow, brown, blue, purple, pink, or colorless. These colors are often so vivid that apatite has frequently been cut as a gemstone. Apatite is a brittle ...
Barite is the primary ore of barium, which is used to make a wide variety of barium compounds. Some of these are used for xray shielding. Barite has the ability to block xray and gammaray emissions. Barite is used to make highdensity concrete to block xray emissions in .

Phosphate Rock. The term phosphate rock (or phosphorite) is used to denote any rock with high phosphorus content. The largest and least expensive source of phosphorus is obtained by mining and concentrating phosphate rock from the numerous phosphate deposits of the world.
