Description

Technical Field

[0001] This invention belongs to the field of non-ferrous metal smelting technology, specifically relating to a copper electrolytic refining anode treatment apparatus and method. Background Technology

[0002] The purpose of copper electrolytic refining is to further purify the anode copper produced by pyrometallurgical refining to obtain high-purity cathode copper and recover valuable metals. The process involves casting pyrometallurgically refined copper into anode plates, using pure copper sheets as cathode plates (or stainless steel, etc.), and alternating these plates in an electrolytic cell. An aqueous solution of copper sulfate and sulfuric acid is used as the electrolyte, and a direct current (DC) power supply is applied. Under the influence of DC current, the copper on the anode and the more negatively charged base metals electrochemically dissolve into the electrolyte, while the precious metals remain insoluble, forming anode sludge that settles at the bottom of the electrolytic cell or adheres to the anode. At the cathode, copper ions gain electrons and crystallize out, yielding the product cathode copper. The anode sludge, containing precious metals and rare metals such as selenium and tellurium, is treated separately as a byproduct of copper electrolysis to recover elements such as gold, silver, selenium, and tellurium.

[0003] During the electrolytic refining process, the anode may be affected by factors such as non-lead weights on the ear, flash, bubbling or nodules, uneven thickness, and deformation, which can affect the distance between the electrolytic electrodes, cause electrolytic short circuits, lead to electrolytic failures, increase power consumption, and affect the amount of electrolyte. This requires the anode to have the following characteristics: (1) full and straight ear, without bending, breakage, or cracks; (2) uniform thickness, high verticality, small bending deformation, and good straightness; (3) small height of bulges or nodules on the plate surface; and (4) small flash and burrs on the edge of the plate surface. However, during the anode casting process: (1) Open mold casting is used, and the bottom of the anode hanging ear has a casting draft angle; (2) The mold is placed on a rotating disc casting machine, and the copper molten metal will cause casting flash due to mold shaking and copper molten metal cooling and shrinkage during the molding process; (3) During the process of pouring copper molten metal into the mold, air will be trapped into the casting liquid, and bubbles will appear after condensation; (4) If the temperature of the casting copper molten metal is too low, or the condensation speed is too fast and the fluidity is poor, it will cause uneven thickness or nodules on the anode copper plate; (5) The condensation and shrinkage of the casting copper molten metal will cause excessive internal stress and deformation, or the top plate will be subjected to force during demolding, resulting in bending and deformation of the anode plate surface; (6) Water cooling is used for anode casting, and rapid cooling will generate large internal stress and deformation; (7) During the hoisting, transportation and storage stacking process, the anode will be deformed due to collision and squeezing. Therefore, before the anode is put into the electrolytic refining tank, it must be prepared by hanging ears, shaping, milling ears and other preparatory treatments to eliminate various influences, improve quality and ensure qualified anode copper. Ultimately, this ensures that the anode is vertical, parallel, equidistant, and centered during the electrolytic refining process, reducing electrolysis failures and power consumption, and improving the quality of electrolytic cathode copper.

[0004] Currently, the anode electrolysis preparation process involves: after anode casting and retrieval, the plates are first water-cooled, then hoisted, stored, and stacked. Next, the plates are flattened, shaped, and have their ears straightened and milled. Finally, they are hoisted, stored, and stacked before being hoisted into the electrolysis tank. In this anode preparation process, the water-cooling process consumes a lot of water and energy, the cooling steam affects operation, increases safety risks, leaks affect the workshop environment, and wastewater requires treatment before discharge, resulting in poor environmental performance. Hoisting and storage involve high labor intensity for workers, require a large area for storage, and pose high safety risks. Flattening and shaping equipment is complex, requires significant investment, has low efficiency, high operating costs, and poor processing results. Ear straightening involves numerous steps, complex equipment, and poor results; ear milling results in tool breakage and severe wear, high operating costs, difficulty in controlling milling precision, damage to the anode surface, reduced anode quality, and high equipment failure rate. Furthermore, the process lacks an edge cleaning step. Summary of the Invention
