摘要： Method and arrangement for producing metal powder. In the method, dissolved utility metal is mixed in a solution containing at least one intermediary metal for precipitating the dissolved utility metal into a utility metal powder (14). In the method, the first part of an acid-containing starting solution is fed on the anode side (6) of an electrolytic cell as anolyte (1), to get in contact with the anode and the supply material containing yield metal, and the second part of the acid-containing starting solution, which also contains intermediary metal, is fed on the cathode side (8) of the electrolytic cell, to get in contact with the cathode (4) as catholyte (3); yield metal is oxidized and dissolved in the anolyte (1) by leading electric current in the anode (2); the yield metal contained in the second part of the starting solution is reduced on the cathode side (8); and anolyte solution and catholyte solution are fed in a precipitating chamber (12) for mixing the dissolved, oxidized yield metal and the second part of the starting solution containing reduced intermediary metal.

摘要： A method and a system of electrowinning, in an electrolytic tank, a metal from an electrolyte that contains a metallic salt. In the method, a diaphragm fabric is selected as the material of the anode bag from a group of diaphragm fabrics with different permeabilities, the dependences of the permeability of the diaphragm fabric on the viscosity of the catholyte and the pressure difference used are defined. On the basis of the defined dependences, the exit velocity of the anolyte from the anode bag is adjusted by the current density that is used, the pressure difference and the viscosity of the catholyte, so that an acid content of the anolyte of at least 50 g/1 is obtained. In the system, a fabric wherein the dependences of its permeability on the viscosity of the catholyte and the pressure difference used are known is selected as the diaphragm fabric of the anode bag from a group of diaphragm fabrics with different permeabilities. The exit velocity of the anolyte is adjusted by the current density used, the pressure difference and the viscosity of the catholyte, so that the acid content of the anolyte that is removed from the anode bag is at least 50 g/1.
