Phosphate mineral - Wikipedia

From Wikipedia, the free encyclopedia

Nickel–Strunz 9 ed mineral class number 8 (isolated tetrahedral units, mainly)

Apatite

Phosphate minerals are minerals that contain the tetrahedrally coordinated phosphate (PO3−4) anion, sometimes with arsenate (AsO3−4) and vanadate (VO3−4) substitutions, along with 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.

Phosphate rock has high concentration of phosphate minerals, most commonly from the apatite group of minerals. It is the major resource mined to produce phosphate fertilizers for the agricultural industry. Phosphate is also used in animal feed supplements, food preservatives, anti-corrosion agents, cosmetics, fungicides, ceramics, water treatment and metallurgy.

The production of fertilizer is the largest source responsible for minerals mined for their phosphate content.

Phosphate minerals are often used to control rust, and to prevent corrosion on ferrous materials applied with electrochemical conversion coatings.

Phosphate minerals include:

Nickel–Strunz classification -08- phosphates[edit]

IMA-CNMNC proposes a new hierarchical scheme (Mills et al., 2009). This list uses it to modify the classification of Nickel–Strunz (mindat.org, 10 ed, pending publication).
