| Abstract | The researches of electrochemical processing of metal wastes and wastes of different alloys under the action of alternate current with industrial frequency (50 cycles per second) have been realized. It has been shown that described condition greatly activated process of anode dissolving compared with process of their chemical oxidation. The solutions of different mineral acids (HCl, HNO3, H2SO4), soda solution, caustic soda and ammonia have been used as electrolytes. The process of electrochemical obtaining of rhenium acid (HReO4) by the way of wastes dissolution of metal rhenium in solution of nitrogen acid has been researched. The technological schemes of electrochemical processing of different W, Mo, Re wastes with obtaining quality commercial products (surface active agents, TiO2, Co3O4, KReO4) have been proposed on the base of realized researches. |
