Get priceApatite is very insoluble and there is relatively little or no fertilizing potential for rock phosphate in unprocessed form. Therefore, phosphorus fertilizers are produced by acidulating rock phosphate, ore containing apatite of either the hydroxyapatite, fluorapatite, or francolite (carbonate) varieties, by one of two general schemes: Either

Get pricePhosphate rock and phosphorite are names used for sedimentary rocks that contain at least 15% to 20% phosphate on the basis of weight. The phosphorous content in these rocks is mainly derived from the presence of apatite minerals. Uses of Apatite as Phosphate Rock.

Get priceApatite is the name given to a group of phosphate minerals that are widely distributed in all rock types, usually in tiny crystals spread throughout the host rock. It is often green in color but can also be blue, or yellow. It can form large crystals in contact metamorphic rocks. It is the mineral that makes up tooth enamel in all vertebrate animals.
