Phosphate deposits are finite resources. According to Sheldon (1982) known deposits of phosphate rock will last about 400 years at current rates of exploitation. Werner (1982) distinguishes between three categories of phosphate resources as shown in Table 1.Reserves are phosphate deposits which under the prevailing economic and technological conditions are worth mining.

• In chemistry, a phosphate is an anion, salt, functional group or ester derived from a phosphoric acid. It most commonly means orthophosphate, a derivative of orthophosphoric acid H 3PO 4. The phosphate or orthophosphate ion [PO 4]3− is derived from phosphoric acid by the removal of three protons H+. Removal of one or two protons gives the dihydrogen phosphate ion [H 2PO 4]− and the hydrogen phosphate ion [HPO 4]2− ion, respectively. These names are also used for salts of those anions...
