Apatite Mineral

Phosphate rock and phosphorite are names used for sedimentary rocks that contain at least 15% to 20% phosphate on the basis of weight. The phosphorous content in these rocks is mainly derived from the presence of apatite minerals. Uses of Apatite as Phosphate Rock. Most of the phosphate rock mined throughout the world is used to produce

Mohs Hardness Scale

Apatite (hydroxylapatite, fluorapatite, chlorapatite) is a group of phosphate minerals and is one of few minerals that are produced by biological organisms. Hydroxylapatite is the major component of tooth enamel. Absolute Hardness: 48. Chemical Composition: Ca. 5 (PO 4) 3 (OH-,Cl-,F-)Mohs. Scale Rank = 5

Hardness of Water - USGS. Water systems using groundwater as a source are concerned with water hardness, since as water moves through soil and rock it dissolves small amounts of naturally-occurring minerals and carries them into the groundwater supply.Water is a great solvent for calcium and magnesium, so if the minerals are present in the soil around a water-supply well, hard water may be

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. Some phosphate rock is used to make calcium phosphate nutritional supplements for animals.

Phosphate Deposits

solubility increases with increasing acidity, decreasing hardness, and decreasing temperature. Apatite may survive rock weather ing for a time to form a phosphate-rich residuum, but it breaks down under prolonged exposure. Some of it may be redeposited locally. In

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

Which Minerals Include Phosphate?

Feb 13, 2019The main test of apatite is by its hardness, which is a 5 on the Mohs scale. Apatite can be cut as a gemstone, but it is relatively soft. Apatite also makes up sedimentary beds of phosphate rock. There it is a white or brownish earthy mass, and the mineral must be

Phosphate Rock

Phosphate rock used for fertilizer is a major NORM due to both uranium and thorium. Phosphate is a common chemical constituent of fertilizer. It is principally mined from apatite and phosphate rocks (phosphorite) in which the concentration of phosphate has been enhanced by sedimentary, igneous, weathering, and biological processes.

Phosphorite

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 rock is enriched (beneficiated) to at least 28%, often more than 30% P 2 O 5.This occurs through washing, screening
