1-12-2004· Phosphorite, phosphate rock or rock phosphate is a non-detrital sedimentary rock that contains high amounts of phosphate minerals.The phosphate content of phosphorite (or grade of phosphate rock) varies greatly, from 4% to 20% phosphorus pentoxide (P 2 O 5).Marketed phosphate rock is enriched ("beneficiated") to at least 28%, often more than 30% P 2 O 5.

Phosphate is an important fertilizer needed for food production. The sources are finite and mining and processing of the ore is an energy intensive and polluting process. Furthermore, sources of phosphate rock in the world are limited to a few countries and Europe is fully dependent on import of this critical resource for its food production.
