Outline
In order to recover uranium from uranium-beryllium flotation tailings and reduce the content of beryllium in uranium products, the occurrence state of uranium and beryllium in uranium-beryllium flotation tailings was analyzed by process mineralogy, and uranium was leached by sulfuric acid leaching process. The effects of acid concentration, leaching time, leaching temperature and liquid-solid ratio on the leaching rate of uranium and beryllium were investigated, and the feasibility of recovering uranium from leaching solution was studied by anion exchange resin. The results show that the uranium in the uranium-beryllium flotation tailings is more easily leached by sulfuric acid, but the beryllium is not easily leached, the uranium can be recovered and the uranium-beryllium can be separated by ion exchange method.
