摘要：
A method has been developed to process waste of tungsten-cobalt solid solutions by potentiostatic dissolution in phosphoric acid solutions. A dissolution mechanism depending on the electrode potential has been proposed. A technique for extracting tungsten from tungsten concentrates in chloride-metasilicate melts has been developed. Conditions for distributing tungsten and ore components between immiscible substances have been established.
