The object of the study is the processes of chemical and electrochemical extraction of tungsten from the pseudo-alloy WC-Co in solutions of acids H2SO4, HNO3, HCl and with the addition of HF. The subject of the study is the kinetic patterns and technological parameters of the interaction of the pseudoalloy WC-Co with solutions of H2SO4, HNO3, HCl with the addition of HF. The dissertation research is devoted to the development of technological indicators of tungsten and cobalt extraction during acid electrochemical opening of WC-Co pseudoalloy. The target products of processing are: tungsten oxide (VI), tungsten powder with a given particle size distribution (2… 3 μm), cobalt electrochemically precipitated.
