Intensification of separation of extraction emulsions in systems with tributyl phosphate in ultrasonic field

The fundamental principles have been studied determining the separation of extraction emulsions appearing in the course of the aqueous and ammonia reextraction of molybdenum from tributylphosphate (TBP) in the ultrasonic field. Piezoelectric radiators with a frequency of 0.8 to 1,0 MHz are used as ultrasonic generators. The organic extract contains 7 g/1 Mo within the hydrosolvate complex. Acceleration of the separation process has been established to take place in the ultrasound region 0.25 to 1.25 W/cm2 for the aqueous and ammonia systems. The optimal conditions for the separation process exist within 0.5 to 0.65 W/cm2, they being 18 minutes for the aqueous and 16 minutes for the ammonia emulsion. It is demonstrated that as a result of the superposition of the ultrasound over the emulsions being formed by TBP with water and ammonia, the separation of the aqueous emulsions increases by a factor of 5 to 6 and of the ammonia emulsions - by a factor of 50 to 80. It is advisable that the ultrasound emulsion treatment for 5 to 10 minutes be coupled with a subsequent settling. As this takes place, the total period of the phase separation will be 18 to 20 minutes. The separation rate increases with temperature. The maximum emulsion separation acceleration is observed within 25 to 30 deg C. The possibility has been revealed to realize the process of the ultrasound intensification of the emulsion separation process by using small-sized extraction equipment
