VANADIUM IN SUDANESE PHOSPHATE A CONTRIBUTION TO THE LOCAL ECONOMY

The results of this study were carried out to determine the composition of the vanadium and uranium elements in the Nuba Mountains area in Southern Kordofan region in the regions of Mount Uro and Mount Kurn. Forty samples were collected from the two regions, 20 samples from each region were grinded and converted into powder, and analyzed by XRF spectrometer to find the concentration of each element in the samples. The analysis showed that the average concentration of the uranium element in the samples of Kurn is 103.27ppm, while the average concentration of samples of the Uro area is 985.13ppm, after the operation of the statistical analysis of the results and the average values shows a significant proportion in the global markets. The metaanalysis process shows high concentration of vanadium with an economic importance of more than 80% in most samples. A statistical analysis of the results of the vanadium was performed. The average concentration of vanadium in the samples is Kurn 2793ppm, while the average concentration of vanadium in the samples of the Uro area is 3667.45ppm. Where the prices of both uranium and vanadium have been shown in the world. Markets, it indicates that these concentrations are very important and can contribute to the economy if used properly. It is very interesting to note that the concentration of uranium and vanadium are proportion to each other. This conforms to the hypothesis that these elements may be produced from molten magma which causes heavy elements to reside at the bottom. The percentage of uranium and vanadium agrees with the radioactive decay law, where the decrease of uranium amount, increases vanadium amount..
