Wet process of uranium extraction technology in metallurgical industry
In the back extraction process of uranium hydrometallurgy industry while it is possible to use ammonium hydroxide and sodium hydroxide from saturated organic phase extraction of uranium, but the generated diuranate precipitation particles is very fine, high concentration of ammonium carbonate and ammonium bicarbonate solution is an effective anti of uranium extraction agent, the uranium compound crystal morphology by complexation extraction into the aqueous phase.
From raising the extraction rate of uranium and coarse grain yield, the concentration of ammonium carbonate is 200 -
250 g/L, using the three-level reverse extraction crystallization back extraction stirring tank in series operation.
running practice proves that the quaternary ammonium salt extraction process short, run steady.
Due to wet the back extraction process of uranium, uranium deposit in the metallurgical industry in alkali bath less impurities, and in the same anion extraction and reverse extraction system, to avoid introducing other impurities anion, make the product quality is higher, and to increase the rate of FanJian created the conditions.
