Abstract
Procédé d'épuration de solutions contenant du carbonate de potassium, du sulfate de potassium, de l'hydroxyde de potassium ou de l'hydrogénocarbonate de potassium, ainsi que principalement, l'un au moins des métaux appartenant au groupe constitué par l'uranium et le molybdène sous la forme de sels de potassium, et des impuretés minérales et/ou organiques, selon lequel on caustifie complètement ou partiellement les solutions précitées par addition d'une quantité adéquate de chaux, on sépare le premier précipité contenant essentiellement CaCO3 et concentre la liqueur séparée par évaporation jusqu'à l'obtention d'une teneur en KOH au plus égale à 50 %, pour provoquer l'obtention d'un deuxième précipité essentiellement constitué par K2 SO4 , puis après séparation de celui-ci, on recueille une liqueur riche en KOH. Ce procédé est plus particulièrement adapté aux traitements des liqueurs issues de l'attaque alcaline de minerais uranifères.Process for purifying solutions containing potassium carbonate, potassium sulphate, potassium hydroxide or potassium hydrogencarbonate, as well as mainly, at least one of the metals belonging to the group consisting of uranium and molybdenum in the form of potassium salts, and mineral and / or organic impurities, according to which the aforementioned solutions are completely or partially caustified by adding an adequate amount of lime, the first precipitate containing essentially CaCO3 is separated and concentrated. the liquor separated by evaporation until a KOH content of at most 50% is obtained, to cause a second precipitate to be obtained essentially consisting of K2 SO4, then after separation of the latter, it is collected a liquor rich in KOH. This process is more particularly suitable for the treatment of liquors resulting from the alkaline attack of uranium ores.
