Apatite Ethically Sourced Healing Stones | Moonrise Crystals

Mining: Apatite is most often mined in massive bedded marine deposits which are mined for phosphorus to be used in fertilizers. Because Apatite occasionally contains 'rare earth minerals', it may also be specifically mined as ore for these rare elements, since, unlike most rare earth ores, Apatite is nonradioactive and does not pose an environmental hazard. Apatite may also be found as an ...

Dec 01, 1980 Because of the high solubility of apatite in basic magmas, phosphorus can be confidently treated as an incompatible element in peridotite melting models. Such models, in combination with observed characteristics of basic lavas, indie that the upper mantle contains ∼200 ppm of phosphorus, much less than the chondritic abundance of ∼900 ppm. get price

Phosphorus (P) in runoff can pose a water quality risk in phosphate mine reclamation areas. High dissolved P (DP) concentrations (about mg L1) in runoff from these areas and high equilibrium P concentrations for the soils led us to hypothesize that P release is controlled by dissolution of apatite rather than by desorption mechanisms.

Apatite is slowly soluble in neutral or alkaline waters, and its solubility increases with increasing acidity. It may survive rock weathering to form a phosphaterich residuum, but it breaks down under prolonged exposure. The PCX content of most river and lake waters ranges from about to part per million (ppm), but may be much higher in soft acid waters and highly saline alkaline ...
