Uranium from Phosphates Phosphorite Uranium

Uranium from Phosphates (Updated May 2020) Rock phosphate deposits contain many million tonnes of uranium, which may be extracted as a by-product of making fertilisers. Some 20,000 tonnes of uranium has already been obtained from these rock phosphate deposits, but the process became uneconomic in the 1990s.

Uranium mining - Wikipedia

Uranium mining is the process of extraction of uranium ore from the ground. The worldwide production of uranium in 2019 amounted to 53,656 tonnes. Kazakhstan, Canada, and Australia were the top three producers and together account for 68% of world uranium production. Other important uranium producing countries in excess of 1,000 tonnes per year were Namibia, Niger, Russia, Uzbekistan and China.

Uranium Mining Overview - World Nuclear

Uranium minerals are always associated with more radioactive elements such as radium and radon in the ore which arise from the radioactive decay of uranium over a few million of years. Therefore, although uranium itself is barely radioactive, the ore which is mined, especially if it is very high-grade such as in some Canadian mines, is handled with some care, for occupational health and safety reasons.

THE IMPACT OF URANIUM NEAR A PHOSPHATE MINING PORT

Jordan is rich in phosphate ore, which was discovered in 1894. The mining and production of phosphate started in1934 in Rusaifeh (Azhar, 2000). The phosphorus content of raw phosphate rock ranges from 30.81 to 33.90% (as P 2 O 5) with the remainder consisting mainly of calcium (50.37-52.20%) as CaO and fluoride (3.53-3.99%).

Uranium from Phosphates Phosphorite

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.

Radiological hazards from uranium mining

Radioactive dust is transferred to the atmosphere by mining operations, extrac-tion and crushing of ore, uranium milling, management of waste rocks and tail-ings. This has to be emphasized because some of the nuclides contained in the uranium decay chains (such has thorium 230) are very radiotoxic when inhaled.
