The world average uranium content in phosphate rock is estimated at 50-120 g/tn. The U concentration ranges 10-27 g/tn in Mongolian phosphate deposits. The aim of this study is to improve quality of the activated phosphorus fertilizer. We decreased uranium concentration from 12g/tn till 3.9 g/tn in the milled phosphate raw by carbonate and citric acid solutions. This work demonstrated that sodium carbonate/bicarbonate uranium leaching process is selective and effective to extract 67,5% of uranium from Burenkhaan phosphate rock.
