Apatite is mineral - common name for a number of related minerals of the apatite group with the common formula Ca5(PO4)3(F, OH, Cl). Mmineral species in the group are fluorapatite (F - up to 3.8), chlorapatite (Cl - up to 6.8), hydroxylapatite, carbonate-apatite. Kola apatite concentrate is a promising and raw material for complex processing, allowing to produce, in addition to the basic product пїЅ phosphoric fertilizers, strontium, rare earth elements and fluorine compounds.
