Production technology for pure uranium compounds

The background, main problems, trends in research and achievements of pure compounds laboratory at the All-Russian Research Institute of Chemical Technology are described. Since its setup in 1953 the Laboratory was engaged in the study, development and introduction at enterprises of uranium industry of uranium precipitation from aqueous solutions, precipitating refining of uranium using carbonate and fluoride uranium and ammonium compounds, thermal decomposition of uranium compounds with preparation of uranium dioxide powders, uranium extraction from solutions and pulps, sorption and extraction of uranium from fluorine-containing solutions, uranium recovery from refuse and waste of fuel element fabrication, liquid radioactive waste treatment
