Abstract
A combined electrochemical and chemical process was developed for the recovery of tungsten and cobalt from hard alloys of VK grades with the preparation of tungstic acid and cobalt oxalate as intermediates. The subsequent reduction of these intermediates in hydrogen yields metal powders of increased purity.
