Phosphate Rock - an overview | ScienceDirect Topics

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.

Mohs scale of mineral hardness - Simple English Wikipedia ...

Mohs' scale of mineral hardness is named after Friedrich Mohs, a mineralogist.Mohs scale is ordered by hardness, determined by which minerals can scratch other minerals.. Rocks are made up of one or more minerals. According to the scale, Talc is the softest: it can be scratched by all other materials. Gypsum is harder: it can scratch talc but not calcite, which is even harder.

What is a Phosphating? - Definition from Corrosionpedia

Mar 16, 2021· What Does Phosphating Mean? Phosphating is a conversion coating that is applied to steel or iron components, and is mostly used as a pretreatment method in conjunction with another method of corrosion protection. The process involves immersing a component in a dilute solution, which then converts the surface of the metal into a layer of microscopic phosphate crystals.
