22-09-2010· Phosphate rock is the primary source of phosphorus – one of three essential plant nutrients. Phosphate concentrate of suitable grade and chemical quality is used to produce phosphoric acid, the basis of many fertilizer and non-fertilizer products. The search for phosphate rock deposits became a global effort in the 20th century.Phosphate Mining - Center for Biological Diversity,24-04-2021· Most mining of phosphate rock involves clearing large swaths of vegetation and digging up the soil beneath to reach the phosphate-ore-containing matrix 60 to 80 feet below the surface. This matrix is then transported by pipeline to a nearby plant, where the phosphate ore is forcibly separated from the sand and clay by a process known as “beneficiation.”Uranium from Phosphates | Phosphorite Uranium - World,,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 .
