الملخص

This study was carried out in order to estimate the concentration ofessential and trace elements and the total content of phosphorus and uraniumin phosphate rocks and to investigate the possibility of using Sudanesephosphate ores as fertilizer.In this study 45 samples of mixed samples of rock phosphate from theeastern part of Nuba Mountains area, western Sudan namely Jebel Kurun nearAbu Jebaiha town was analyzed.Two different types of techniques namely atomic absorptionspectrometry (AAS) and UV spectrophotometry were used for measurementof concentrations of 16 elements in phosphate rocks. The mean values ofconcentration of the elements in Kurun phosphate were found to be:(Na:0.500%), (K:.0.525%), (Mg:O.425%), (Ca:l1.845%), (Ni:0.l25%),(SiO;:22.865%), (Al:18.030%), (Fe:7.300%), (Ti:0.095%), (Mn: 420ppm),(Zn: 570ppm), (Cu: 281ppm), (Pb; 275ppm), (Co: 300ppm), uranium13 lppm. ARock phosphate ores mixed samples were analyzed for their totalphosphorus content measured as P2O5% using colorimetry. The averageconcentration of total phosphorus was found to be 24.8%. The percentages aresuitable for using the ore for production of fertilizer or phosphoric acid. "The trace uranium level content was found to be l31ppm; this range isreasonable when it is compared with similar data for phosphate ore fromdifferent areas in the world. The results obtained were compared with the datafrom literature and they showed a good agreement. The best conditionsneeded to obtain the highest percentage of available phosphorus, which is111
