Purposefulness of the uranium(VI) flotoextraction isolation from their diluted nitrate, sulphate and carbonate solutions in the presence of electrolyte additions using the thin-emulsified solution of the trialkylamine in white spirit has been found. It has been shown that in the presence of electrolyte additions uranium compound isolation degree decreased by 10—15%, optimal pH range got narrow and displaced to neutral medium, the collector optimal consumption decreased considerably, rate constants increased into 1,5—2 times. High efficiency of the uranium(VI) flotoextraction isolation has been showed by tests carried out on carbonate and sulfate model solutions.
