Abstract

The method for electroextraction from solutions includes periodically treating the solution in a cylindrical electroreactor (1). The reactor has six cylindrical steel electrodes that are fed with three-phase alternating current of commercial frequency (10), which can be pulse. Each phase of the three­phase current is connected to three electrodes of one triode stacke or in parallel to two triode stacks. The parallel connection of three-phase current to two triode stacks is performed so that the same phase of the three phase current is connected in parallel with each two opposite electrodes of six electrodes located along the periphery, or with two adjacent electrodes. A bipolar stationary aluminum electrode is situated in the inter-electrode space. Non-ferrous metals are extracted in a form of ferrite-chromites, and aluminates as well as hydroxyl salts deposited in the inter-electrode space. Deposits are separated from solution by known methods of filtration (14).
