| Abstract: | The optimum conditions of seperating uranium from boron in carbonate decomposition of uranium bearing boron concentrate were studied in the paper. The uranium bearing boron concentrate was roasted in the reduced atmosphere with CO and the concentrate roasted had activity of 90 83%. The concentrate roasted was decomposed in the aqeous solution of sodium carbonate with CO 2,the leaching rates of uranium and boron were 4 88% and 86% respectively. When a little redutant FeS was added to the decomposing system,the Leaching rate of urarium was decreased to 0 62% and the rate of boron was still more than 86%. |
