Problems solved by technology

In order to reduce the amount of remnant electrode plates returned to the furnace, each factory generally controls the remnant electrode rate at 13-20%. There will be breakage and falling, which will firstly cause a short circuit of the electrode, affect the quality of cathode copper, and affect the electric efficiency; secondly, it will damage equipment such as electrolytic cells or units; thirdly, there will be no thick copper / residual plate electrode wires in the corresponding part of the cathode , the part of the cathode no longer grows copper
At present, the industry has not proposed a better improvement method for the above-mentioned problems that occur during the use of thick copper / residual plate plates

Embodiment Construction

[0010] A hybrid electrolysis system for producing cathode copper, comprising an electrolytic cell 10 and an electrolyte in the cavity of the electrolytic cell 10, two parallel notch edges of the electrolytic cell 10 are laid with negative and positive conductive busbars 11, 12. The hybrid electrolysis system for producing cathode copper also includes a cathode 20 arranged in parallel along the length direction of the electrolytic cell 10 and a dedicated anode 30 for the hybrid electrolysis method. 11 and 12 are electrically connected, and the dedicated anode 30 for the hybrid electrolysis method is hung with a crude copper / residual plate 40, and the crude copper / residual plate 40 is immersed below the liquid level of the electrolyte. The thick copper / residual plate 40 can be caught by the special anode 30 for the mixed electrolysis method, so that the blister copper / residual plate 40 can be fully immersed in the electrolytic solution.

[0011] Preferably, the method of hanging...

Abstract

The invention belongs to the technical field of smelting, and particularly relates to a mixed electrolysis system for producing a cathode copper; the mixed electrolysis system comprises an electrolytic bath and electrolyte in an electrolytic bath cavity; two bath openings in parallel of the electrolytic bath are paved with cathode and anode conducting busbars along the length direction; the mixed electrolysis system for producing the cathode copper further comprises a cathode and a mixed electrolytic process special anode which are arranged in parallel along the length direction of the electrolytic bath; the cathode and the mixed electrolytic process special anode are electrically connected with the cathode and anode conducting busbars; the plate body of the mixed electrolytic process special anode is obliquely hung with a coarse copper / residual electrode plate. The mixed electrolysis system for producing the cathode copper can direct recycle the residual polar plate, or completely apply the course copper to produce the high purity cathode copper; thus the mixed electrolysis system can eliminate the re-melting procedure of the residual polar plate, shorten the copper smelting technical flow, and save huge cost and high energy consumption for re-melting the residual polar plate.

Description

technical field [0001] The invention belongs to the technical field of smelting, and in particular relates to a mixed electrolysis system for producing cathode copper. Background technique [0002] In the existing copper electrolytic refining production, all are to directly use blister copper as blister copper / residue plate to produce cathode refined copper. In order to make the cathode of the whole electrolysis process have a corresponding thick copper / residual plate electrode line, the thick copper / residual plate cannot be fully electrolytically utilized, so a remnant plate is produced. At present, the butt plates can only be reused by returning to the furnace and recasting, but the cost of returning to the furnace is extremely high. According to statistics, for a copper smelter with a production capacity of 400,000 tons, the investment in the construction of the scrap treatment process exceeds 30 million yuan, the annual processing scrap exceeds 70,000 tons, and the annu...
