Phosphate Rock - an overview | ScienceDirect Topics

Phosphate rock (phosphorite) is a marine sedimentary rock that contains 18–40% P 2 O 5, as well as some uranium with all its decay products, often 70–200 ppm U, 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. This is insoluble, so ...
