Phosphate rock is used for both unprocessed phosphate and beneficiated phosphate. In phosphate fertilizer terminology, phosphate ore usually refers to unprocessed phosphate from the mine, and rock concentrate usually refers to the beneficiated phosphate suitable for further downstream processing into phosphoric acid and other phosphate products.
Phosphate rock is the only significant commercial source of the element phosphorus. It consists of the calcium phosphate mineral apatite together with quartz, calcite, dolomite, clay, and iron oxide as the so-called gangue constituents.
