The electrolytic recovery of metals with insoluble electrodes leads to the oxidation of the anions in the solution, which, for example with chlorides, can lead to the formation of chlorine and to an attack on the anodes and other materials. With corresponding ion exchanger membranes, these types of ions can be kept away from the anode while the current keeps flowing.

General process description ReMem

This operation is employed with chloride-containing metal solutions on the one side as catholyte, and on the other side of the membrane as a chloride-free anolyte. The compartment of the insoluble anode with the ion exchanger membrane can be employed as "insoluble anode" for working on metal-rich solutions.

The membrane electrolysis cell serves for the recovery of nickel from chloride-containing solutions and for separating zinc and tin or lead-tin.

Different sizes are available. The compact system is supplied ready for connection.
