    Use in fertilizers: - • Superphosphate fertilizers are produced by treatment of phosphate rock with acids. Using phosphoric acid, fluorapatite is converted to Ca(H2PO4)2: Ca5(PO4)3F + 7 H3PO4 → 5 Ca(H2PO4)2 + HF • This solid is called triple superphosphate. Several million tons are produced annually for use as fertilizers.
