Embodiment Construction

[0058] Figure 1 to Figure 10 A first electrolytic cell 10 for performing manganese metal electrolysis or "MME" according to the invention is shown.

[0059] with manganese ions Mn 2+ Manganese metal is formed on a plurality of cathodes by supplying an electric current in the presence of contact with the raw material solution, optionally in the presence of ammonium sulfate.

[0060] Thus, the formed manganese metal is deposited as a solid on each cathode.

[0061] The electrolytic cells 10 are placed in a device comprising several electrolytic cells 10 connected in series, for example about 100 electrolytic cells 10 .

[0062] Such as figure 1 As shown, electrolytic cell 10 includes a tank 12 defining an interior space 14 and an inner box 16 of the "filter press" type disposed within interior space 14 of tank 12 .

[0063] According to the invention, the electrolytic cell 10 also includes an assembly 18 for enclosing an inner space for trapping and hermetically conveying the...

Abstract

The invention relates to a box comprising a plurality of anode frames (66), a plurality of cathode frames (64) placed between the anode frames (66) and a plurality of diaphragms (68) disposed between each cathode frame (64) and each anode frame (66). Each cathode frame (64) delimits an inner cathode-receiving compartment (90) and at least one lateral supply opening (96) for supplying a feed solution containing manganese ions to the inner compartment (90). Each cathode frame (64) defines an upper lateral opening (98) for discharging cathode gases and said upper discharge opening (98) is disposed above the or each lateral supply opening (96) for the feed solution so that the discharge opening opens at least partially above the feed solution.

Description

technical field [0001] The invention relates to an inner box of an electrolytic cell for manganese electrolysis, the inner box is used to be placed in a tank containing a raw material solution, and the inner box includes: [0002] - multiple anode frames; [0003] - a plurality of cathode frames placed between said anode frames; [0004] - a plurality of separators interposed between each said cathode frame and each said anode frame; [0005] - a clamping assembly capable of maintaining said cathode frame, said anode frame and said separator in close proximity to each other, [0006] Each of said cathode frames defines an inner compartment accommodating a cathode, an upper cathode introduction hole in said inner compartment, and at least one side hole for supplying a raw material solution containing manganese ions into said inner compartment . [0007] This box is intended to be removably inserted into the tank of a manganese electrolytic cell. Background technique [0...
