Positive effect of anion collectors additives — alkylcarboxylates potassium (ACP) on process of tributylphosphate (TBP) flotation isolation from its emulsions is positioned. Optimum ACP is 14 mg/dm3. The most effective collector is potassium myr-istate in which presence the maximum degree of extraction (amax) desired conditions of experiment is 90 %. Bulk TBP (75-95 % from a ) is extraction for the first 10 min of a flotation. The kinetics of flotation process is described by the equation of the first order. Values of kinetic constants lay within 0,04-0,08 min-1. The time necessary for achievement a is 20-25 min. The fullest TBP is extraction from alkaline medium (pH 9-12).
