Kovdorskite
Kovdorskite, Mg2PO4(OH)·3H2O, is a rare, hydrated, magnesium phosphate mineral. It was first described by Kapustin ''et al.'',Kapustin, Y. L., Bykova, A. V. & Pudovkina, Z. V. (1980). Zap. Vses. Mineral. Ova. 109, 341-34/ref> and is found only in the Kovdor Massif near Kovdor, Kola Peninsula, Russia. It is associated with collinsite, magnesite, Dolomite (mineral), dolomite, hydrotalcite, apatite, magnetite, and forsterite. References {{reflist Further reading *Subbotin, R. P. L. V.

Phosphate Minerals
Phosphate minerals contain the tetrahedrally coordinated phosphate (PO43−) anion along sometimes with arsenate (AsO43−) and vanadate (VO43−) substitutions, and chloride (Cl−), fluoride (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. Applications Phosphate rock has high concentration of phosphate minerals, most commonly of the apatite group. It is the major resource mined to produce phosphate fertilizers for the agriculture sector. Phosphate is also used in animal feed supplements, food preservatives, anti-corrosion agents, cosmetics, fungicides, ceramics, water treatment and metallurgy. The largest use of minerals mined for their phosphate content is the production of fertilizer. Phosphate minerals are often used for control of rust and prevention of corrosion on ferrous materials applied with electrochemical co ...
