Phosphate Rock | Minerals Education Coalition

Phosphate Rock. The term phosphate rock (or phosphorite) is used to denote any rock with high phosphorus content. The largest and least expensive source of phosphorus is obtained by mining and concentrating phosphate rock from the numerous phosphate deposits of the world.

Phosphate and How Florida Was Formed

Fertilizers - Safer Phosphates

A less common occurrence of phosphate is in igneous deposits. Formed through the cooling of lava, igneous rocks usually contain fluorapatite. Whereas fluorapatite is simpler to process, its hardness requires blasting and comminution, which impacts on operating costs.

Use of phosphate rocks for sustainable agriculture - fao.org
