phosphorous content of apatite

Apatite Wikipedia

Phosphorite is a phosphate-rich sedimentary rock, that contains between 18% and 40% P 2 O 5. The apatite in phosphorite is present as cryptocrystalline masses referred to as collophane.

Phosphorus and the rare earth elements in felsic magmas

Apatite saturation occurs at levels of dissolved P 2 O 5 ranging between 0.04 (± 0.02) and 0.28 (± 0.13) wt%. with only 4 values outside the 0.09–0.20 wt% range. The results demonstrate not only that apatite is a common liquidus phase in felsic melts, but also that, under most circumstances, it remains in the residue during episodes of partial fusion of the crust.

Phosphorus removal from wastewater by mineral apatite

01/08/2006· Natural apatite has emerged as potentially effective for phosphorus (P) removal from wastewater. The retention capacity of apatite is attributed to a lower activation energy barrier required to form hydroxyapatite (HAP) by crystallization. The aim of our study was to test the P removal potential of four apatites found in North America.

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

High P–T Stability of Hydroxyl-apatite in Natural and

If it is assumed that the bulk P 2 O 5 content of 0·2 wt % in an average MORB is stored in apatite then only 60% of the apatite will have broken down by the time the P–T conditions of the apatite–tuite breakdown are reached. In rocks with a higher bulk P content the persistence of apatite is even more likely. It has to be emphasized, however, that this calculation is valid only for
