First Evolutional Liquid-liquid Extractor <New Sale>
Emulsion Flow (EF)

Recovery of rare metals such as rare earth, Ni, Co, Li, and U from urban mine, waste waters, natural water, etc.
●Removal of toxic elements such as B, As, and radioactive elements from waste waters, drinking water, brine, etc.
●Removal of sludge, oil, and surfactant from waste water of water-based paint, oily waste water, washing waste water, etc.
EF apparatus is produced based on the patent of the Japan Atomic Energy Agency (JAEA)

We can supply the EF extractor from a testing apparatus to a factoy practical use apparatus at your request.

Characteristic of EF extractor

Low Initial and Running Cost

 ・Simple Configuration and Operation by the

  Liquid Flow with Pump only


 ・Small Size but Large Volume Processing Ability

Easy Operation

 ・On/off of Pump and Open/close of Valve only

No Oil Leakage

 ・Perfect Phase Separation)



Schematic flow of EF extractor operation

Aqueous phase is sprayed from the upper head and organic phase from the bottom head. Mixing and separation of aqueous phase and organic phase can be controlled only by the counter- current flow of both liquid with the pump. Phase separation is occurred simultaneously with extraction. 


Testing Apparatus CMC-EF1





Practical use example of EF extractor
@Mixed oxide of Nd and Dy recovered from Nd magnet scrap has been processed by the EF extractor for the separation of Dy and Nd-Pr up to 99.9% grade using PC-88A in kerosene. (CMC company)
