Description

Technical Field

[0001] The utility model relates to the technical field of copper electrolysis test platforms, in particular to an industrial-grade test platform in the copper electrolysis process. Background Art

[0002] During the pyrometallurgical smelting process, copper concentrate undergoes smelting, blowing, and pyrorefining, resulting in anode copper content of only 98.8% ≤ Cu ≤ 99.5%. This quality does not meet the requirements of electrical and other industries. Therefore, nearly all crude copper undergoes electrolytic refining to remove impurities that are difficult to remove during pyrorefining. Electrolytic refining involves using pyrorefined anode plates as anodes and starting plates as cathodes. These plates are alternately placed in an electrolytic cell, where a mixed aqueous solution of copper sulfate and sulfuric acid is used as the electrolyte. Under the influence of direct current, the copper on the anodes and base metals with a more negative potential dissolve into the process fluid, while precious metals and other impurities remain insoluble, forming anode mud and sinking to the bottom of the cell. Copper in the process fluid is preferentially precipitated at the cathode, resulting in a high-purity copper, known as cathode copper. Due to the inconsistent sources of anode plates, the impurity content is unstable and often exceeds the standard, leading to varying degrees of quality issues in the physical appearance and chemical composition of the cathode copper. To address the above issues, the production system electrolytic cells were separated from the overall electrolyte circulation, and a small circulation system was added to serve as a test platform for different anode plates. The anodes used included both purchased anodes and purple-mixed anode plates. Industrial trials were conducted, sampling anode plates from the same batch and placing them in several test tanks. The amount of additives added, electrolyte temperature, electrolyte flow rate, and current density were controlled to determine the optimal process parameters for each batch of anodes. Based on this, a process parameter database for different anodes was established. Through data accumulation and relying on big data technology, the production process was intelligently controlled.
