Recovery of tungsten and cobalt from secondary raw materials by a combined electrochemical and chemical procedure

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...

Description
Summary: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.
