Phosphate Minerals - an overview ScienceDirect Topics

Phosphate mineral formation represents another phosphorus sink that is influenced by microbial activity; however, it encompasses processes other than cellular assimilation and short-term storage of phosphorus as biological molecules. In mineral formation (also called phosphogenesis), phosphate anions react with cations in the environment to form insoluble precipitates.

Phosphate Mineral - an overview ScienceDirect Topics

Phosphate Mineral. Phosphate minerals are natural sources of thorium, uranium, and uncommon metals and are also used in the radiochemical methods of separation of fissile materials from irradiated nuclear fuel and processes of “excess” weapon plutonium conversion into the mixed oxide fuel (MOX) for the nuclear reactors of new generation.

The Influences of Magnesium upon Calcium

In temperate soil ecosystems, the solubility-limiting solid-phase phosphate mineral is often predicted to be hydroxyapatite (HAP; Ca 5 (PO 4) 3 OH). A number of analogues exist with varying degrees of crystallinity and solubility: amorphous, calcium deficient, and carbonate substituted [ 1 ]; all are strongly favored to form at neutral to basic pH system and a Ca:P ratio greater than 1.67:1.
