Embodiment Construction
[0010] A method for energy saving and consumption reduction of electrolytic manganese metal, the method comprises the following steps: 1. preparing (certainly including purchasing qualified ones prepared by others) manganese sulfate (MnSO 4 ) solution as the electrolyte; ② in the manganese sulfate (MnSO 4 ) solution by adding the electrolytic additive selenium dioxide (SeO 2 ); ③ In the electrolytic cell, selenium dioxide (SeO 2 ) of manganese sulfate (MnSO 4 ) solution to be electrolyzed to obtain electrolytic metal manganese accumulated on the electrolytic cathode plate; ④ take out the electrolytic cathode plate with electrolytic metal manganese, passivate, rinse, and dry; finally, peel off the electrolytic cathode plate from the electrolytic cathode plate Electrolytic metal manganese sheets (the above steps are the same as the prior art, and the materials used for the cathode plate and the anode plate are also the same as the prior art. Therefore, they will not be describ...

Abstract
The invention discloses an energy-saving method for electrolyzing metal manganese. In electrolytic process, an impulse power source is adopted, wherein the impulse frequency of the impulse power is 900-1200Hz, the duty cycle thereof is 40-80%, and the average current density thereof is 380-420A / m<2>. During the electrolytic process, an anode plate is an electrode plate with a plurality of concavepits, the diameters of the plurality of the concave pits are 0.5-2.5mm, the center distance between the concave pits is 2-9mm, and the depth of the each concave pit is 0.5-2.5mm. The method can improve current efficiency, and the test shows that the current efficiency is improved to more than 80% compared with the current efficiency being not more than 75%. The method can reduce the generating amount of anode mud in an anode area so as to prolong the service life of the anode plate, reduce the times for cleaning slots, obtain the beneficial effect of saving energy, and naturally and greatly reduce the cost for electrolyzing the metal manganese.
Description
technical field [0001] The invention relates to an electrolysis method for electrolysis of manganese metal. Background technique [0002] Metal manganese (Mn) is not only an important raw material for the production of stainless steel, high-strength alloy steel and non-ferrous metal alloys such as copper and aluminum, but also widely used in the fields of medicine and chemical industry. Considering various factors such as product purity, effective utilization of mineral resources, energy saving, and less environmental pollution, at present, electrolysis is mostly used to produce metal manganese. The existing electrolytic manganese metal adopts direct current electrolysis, and the current efficiency is less than 75%. During the electrolysis process, the anode slime in the anode area is also relatively large, thereby blocking the diaphragm bag, increasing the number of cleaning tanks, and reducing the service life of the anode . Contents of the invention [0003] The first...
