Jun 24, 2016· Phosphate rock (PR) is an important mineral resource with numerous uses and applications in agriculture and the environment. PR is used in the manufacture of detergents, animal feed, and phosphate (PO 4 3–) fertilizers.Leaching or runoff losses from PR products like PO 4 3– fertilizers, animal feeds, and detergents could cause eutrophication of surface waters enriched in PO 4 3– by .

Phosphate rock is a general term referring to rock with high concentrations of phosphate minerals, most commonly those of the apatite family with the general formula Ca 5 (PO 4 CO 3) 3 (F,OH,Cl). Ninety percent of phosphate mined is used to produce chemical fertilisers.
What is Monazite? Monazite is a rare phosphate mineral with a chemical composition of (Ce,La,Nd,Th)(PO 4,SiO 4).It usually occurs in small isolated grains, as an accessory mineral in igneous and metamorphic rocks such as granite, pegmatite, schist, and gneiss.These grains are resistant to weathering and become concentrated in soils and sediments downslope from the host rock.

Phosphate minerals contain the tetrahedrally coordinated phosphate (PO 4 3−) anion along sometimes with arsenate (AsO 4 3−) and vanadate (VO 4 3−) substitutions. Chlorine (Cl −), fluorine (F −), and hydroxide (OH −) anions that also fit into the crystal structure.. The phosphate class of minerals is a large and diverse group, however, only a few species are relatively common.
