Particulate emissions occurring from phosphate rock handling are discussed in Section 11.21, Phosphate Rock Processing. 8.9.3.2 Thermal Process - The major source of emissions from the thermal process is H3PO4 mist contained in the gas stream from the hydrator. The particle size of the acid mist ranges from l.4 to 2.6 micrometers. It is
Phosphate fertilizers are obtained by extraction from phosphate rock, which contains two principal phosphorus-containing minerals, fluorapatite Ca 5 (PO 4) 3 F (CFA) and hydroxyapatite Ca 5 (PO 4) 3 OH. These minerals are converted into water-soluble phosphate salts by treatment with sulfuric (H 2 SO 4) or phosphoric acids (H 3 PO 4).The large production of sulfuric acid is primarily motivated ...
