RECOVERY OF TUNGSTEN AND COBALT FROM HARD ALLOY WASTES BY THE ELECTROCHEMICAL METHOD - article

The electrochemical process has been investigated, and a method for the recovery of tungsten and cobalt from wastes of hard alloys, which are widely used in metal-working industry, containing tungsten carbide and cobalt, has been developed. The method is simple, enables the recovery of tungsten and cobalt in one stage, is wasteless and does not pollute the environment with heavy metals. Product that are obtain: tungstic acid, tungsten and cobalt powders, which have high purity and can be used repeatedly in the fabrication of hard alloys.

Key words: tungsten, cobalt, hard alloys, electrolysis.
