The known natural phosphate minerals exceed 250 in number (Fisher 1973). However, the more common ones are small in number and belong to the apatite family. This family constitutes the main group of primary phosphates of the lithosphere. The majority of the other minerals result from a supergene alteration by groundwaters, or bat- and -guanos.
