锆冶炼废渣中铀、钍的浸出试验研究
Leaching of Uranium and Thorium from Zirconium Metallurgical Waste Residue
摘要
Abstract
Zircon sand often contains minerals such as kyanite,thorite and thorianite,which contain trace amounts of radioactive elements such as uranium and thorium.During the production of zirconium oxychloride,these radioactive elements are concentrated in the waste residue,which has certain recycling value.To meet the demands of comprehensive utilization and radioactive pollution control of such waste residues,the process conditions for extracting valuable elements such as uranium and thorium from the waste residues were studied,and the effects of different leaching factors and parameters on the leaching efficiency of uranium and thorium were investigated.The results show that under the conditions of sulfuric acid concentration of 4 mol/L,leaching time of 4 h,liquid volume to solid mass ratio of 4∶1,and leaching temperature of 90 ℃,the leaching rates of uranium and thorium reach 99.9％and 88.6％,respectively.The result is better.关键词
