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, which contains high concentrations of apatite-group minerals, serves as the primary economic source for phosphorus extraction. The majority of mined phosphate minerals are utilized in the agricultural industry for the production of fertilizers and animal feed supplements. Beyond agriculture, these minerals are employed in industrial applications including water treatment, metallurgy, food preservation, ceramics, and cosmetics. Additionally, phosphate compounds are commonly utilized in electrochemical conversion coatings to control rust and inhibit corrosion on ferrous materials.

Phosphate minerals include:

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).
