Summary
A new process is given for the chemical separation, simply and economically, of the uranium contained in solutions formed by sulfuric acid attack of low uranium content ores. The attacking solution is processed in two stages. The solution is neutralized to pH 2.7 to 3 with milk of lime and a portion of the dissolved impurities are precipitated. Then milk of lime of the uranium is precipitated at to pH 6.5 to 7. The uranium concentrate is then subjected to controlled sulfuric attack for its total reduction to a solution containing a mininum of foreign ions. The uranium solution thus obtained is purified by extraction with TBP. (auth)
