Method of recovering zinc using a water-in-oil emulsion |
| abstract |
A method of removing zinc ions from waste water comprises contacting the water in counterflow with a water-in-oil emulsion, said oil acting as a membrane and containing an organic phase-transfer aid. Dezinced water is removed from the system, the emulsion is broken in an electrostatic field to render a zinc- rich aqueous phase and an oily phase which is recycled to form a fresh emulsion. |
