Phosphate Rock

Phosphate Rock

+

Rock phosphate is a naturally occurring ore of marine sedimentary origin. It may have a composition of 0300, but the grade is noted as 030, since rock phosphate is sparingly soluble and little of the phosphorus is available to crops. Many of the mines that produced rock phosphate are closed, and most of the marketed rock phosphate comes from other phosphate mines. The crushed ore is washed ...

Phosphate rock (phosphorite or rock phosphate) contains 15–20% phosphate bearing minerals. The phosphorus is present as fluorapatite—Ca 5 (PO 4) 3 F—or as hydroxyapatite (apatite)—Ca 5 (PO 4) 3 OH. Another source is dissolved phosphate minerals from igneous and metamorphic rocks. Phosphate rock is a nonrenewable resource that takes 10–15 million years to cycle naturally. All crops ...
