phosphate ore rock

Phosphate rock (phosphorite) is a marine sedimentary rock which contains 18-40% P 2 O 5, as well as some uranium and all its decay products, often 70 to 200 ppmU, and sometimes up to 800 ppm. The main mineral in the phosphate rock is apatite, and most commonly, fluorapatite – Ca 5 (PO 4) 3 F or Ca 10 (PO 4) 6 (F,OH) 2.

Phosphate rock is extracted from open-pit and underground mines, depending on the geological and morphological properties of the phosphate ore. Generally, the extraction from open-pit mines generates dust emissions and produces large quantities of mine waste with 1–12 tons of waste extracted per 1 ton of phosphate ore ( Taha et al., …

The mined rock phosphate ore is then processed through a beneficiation process to separate the phosphate mineral from other minerals and impurities. This can involve various methods such as washing, flotation, or magnetic separation. Production of phosphoric acid.

Phosphate rock (PR) is an important strategic material, providing the non-renewable elemental resource phosphorus (P). From the view of geosciences, PR can actually be seen as a special rock rich in the element P. Many studies have reported on PR distribution, but there is little predictive geological research from a metallogenic perspective on the …
