Phosphorite - Wikipedia

01-12-2004· 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.

Phosphate Adsorption on Hematite, Kaolinite, and …

01-08-1997· In mixed system the model reproduced the shape of the adsorption isotherms well over the pH range 3.8–9.0. However, phosphate adsorption was overestimated. The hematite and the kaolinite–hematite system were synthesized and identified by X-ray, NMR, and FT-IR spectroscopy.

Ab Initio Studies on Hematite Surface and the Adsorption ...

This investigation explores the ab initio DFT method for understanding surface structure of hematite and the nature and energetics of phosphate adsorption. Using the full potential linearized plane wave method (FP-LAPW), we derived the structure and energies of various magnetic forms of hematite. The antiferromagnetic (AFM) form was observed to be the most stable.

PHOSPHATE ROCK

Phosphate rock is obtained from geological deposits. Its primary constituent is apatite, a calcium phosphate mineral. Phosphate rock is the basis material for almost all phosphate fertilizers, either as such or transformed into phosphoric acid. When added to the soil, phosphate rock slowly dissolves and gradually releases its nutrients.
