Phosphate Rock F

Fertilizer Wikipedia

The most popular phosphate-containing minerals are referred to collectively as phosphate rock. The main minerals are fluorapatite Ca 5 (PO 4) 3 F (CFA) and hydroxyapatite Ca 5 (PO 4) 3 OH. These minerals are converted to water-soluble phosphate salts by treatment with sulfuric (H 2 SO 4) or phosphoric acids (H 3 PO 4).
