Africa is a source of many phosphate deposits of various resource grades and a significant global contributor of phosphate for fertilizer or phosphoric acid applications. Many of these deposits in Africa exist as sedimentary and alluvial deposits. The main phosphate bearing mineral is usually carbonate fluorapatite with quartz occurring as the main gangue mineral.

Three quarters of the world''s phosphate deposits are of sedimentary origin and 75%–80% of those include carbonate gangue. In this study, carbonate sedimentary phosphate deposits of the Lar Mountains of southwest Iran are studied. These deposits consist mainly of calcite, fluorapatite, quartz, kaolinite and illite, with an average P2O5 grade of 9%–10% (lowgrade).

Although the phosphate resources in China are abundant, they mainly consist of lowgrade phosphate rock. The beneficiation of lowgrade phosphate ores is also a worldwide problem, and effective technologies to process such ores are yet to be developed. As a result, most lowgrade phosphate rocks are currently unexploited.
