Keywords: Uranium series, Phosphate ore, Beneficiation, Gammaray spectrometer, ICPMS. 1 Introduction Phosphate ores are normally in the form of calcium phosphates Ca 3 (PO 4) 2 (phosphorites), which are very old marine deposits associated with fossils. This form of phosphate ore represents about 85% of the worldwide production.
Uranium mining in the United States produced 173,875 pounds ( tonnes) of U 3 O 8 in 2019, 88% lower than the 2018 production of 1,447,945 pounds ( tonnes) of U 3 O 8 and the lowest US annual production since 1948. The 2019 production represents % of the anticipated uranium fuel requirements of the US''s nuclear power reactors for the year.
URANIUM RESOURCES IN PHOSPHATE ROCK The world average uranium content in phosphate rock is estimated at 50 200 ppm. Marine phosphorite deposits contain averages of 6 120 ppm, and organic phosphorite deposits up to 600 ppm. World uranium resources in phosphate rock are not very well known; the following table shows approximate inventories.

Uranium mining is the process of extraction of uranium ore from the ground The worldwide production of uranium in 2015 amounted to 60,496 tonn
#0183;#32;The uranium concentrations in phosphate ores in the world vary regionally and most countries with large phosphate deposits have either plant in operation to extract uranium or are at the stage of pilot extraction plants.
Phosphate rock (phosphorite) is a marine sedimentary rock which contains 1840% 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.

Agricultural applications of chemical fertilizers are a world wide practice. The specific activity of uranium238 and heavy metals (As, Cd, Cu, Pb and Se) in phosphate fertilizers depends on the phosphate ore from which the fertilizer produced and on the chemical processing of the ore.

uranium recovery locally from phosphate ore in order to use this byproduct as a fuel in nuclear power and desalination plants in the future. In order to address this issue, different measurement techniques were used in this study to determine the concentration of uranium in various phosphate rocks.
Extracting uranium from phosphates use to be an uneconomic process in and of itself except as a byproduct of other processes. However, since the 1990s, the economics have changed in favor of uranium, with yellowcake on the spot market near 100/pound.

Uranium Recovery from Phosphates
Iron ore is a massive scale operation around the world, with iron ore being used in iron and steel production, which are important materials in many of the building we build and things we do. Mining companies and iron ore projects, like the other forms of mining, have been cleaned up in the past years and is today, much safer and cleaner than it was.

the chemical analyses of phosphate fertilizers products including; single super phosphate SSP, phosphate ore, triple super phosphate TSP, and byproduct of phosphogypsym. P2O5 content was found between 8 to 15 ppm are within the range 4 and 38 % P2O5 that was reported in other phosphate ores(9). Uranium ions was found in the range to
#0183;#32;Phosphate ore samples were collected, and analyzed for uranium abundance. The results showed that the samples contain a significant concentration of uranium with an average of g/g, which is times higher than the world average of phosphate.
