Copper cathode production and processing process manufacturing method and equipment
Copper cathode is electrolytic copper. Electrolytic copper is the purification of copper metal by electrolysis, in which copper dissolves into copper ions from the anode and moves toward the cathode, and then gains electrons when it reaches the cathode and precipitates pure copper at the cathode, so electrolytic copper can also be called cathode copper.
The method developed by SUNY GROUP for producing high purity copper cathode includes the following steps.
1) Preparing electrolyte, electrolyte ion concentration ;
2)Use stainless steel plate as the cathode, the cathode side covered with clamping strips or other insulating materials, the cathode as a whole placed in a frame made of insulating material, the distance between the frame and the surface of the cathode ≧ 60mm, the frame is wrapped by 200 mesh or more filter material;
3)Maintain the uninterrupted circulation of electrolyte and electrolyte temperature stability, electrolyte circulation process, at least two filtration processes for the full circulation amount of electrolyte;
4) The electrolyte after multiple filtration processes is the cathode solution, which is transported through the pipeline directly into the cathode frame for electrolysis production;
5) Before the impurity ion concentration reaches the upper limit of the technical control index, the solution is extracted for purification treatment. This technology provides a method of producing high purity copper cathode, which realizes the production of high purity copper cathode with mature technology of production and purification process and low production cost.
Electrolytic copper equipment:
Electrolytic copper equipment includes special pulse power supply, electrolytic tank, storage tank (for storing circulating potion), circulation setting , other electrolytic tank accessories (cathode and anode output cables, several copper rows, anode plate, cathode plate, copper hooks, etc.).
Working principle of copper electrolysis equipment:
Copper purification by electrolysis: the rough copper (containing 99% copper) is pre-made into a thick plate as the anode, the pure copper is made into a thin sheet as the cathode, and the mixture of sulfuric acid (H2SO4) and copper sulfate (CuSO4) is used as the electrolyte. After being energized, copper dissolves into copper ions (Cu) from the anode and moves to the cathode, where it gains electrons and precipitates pure copper (also called electrolytic copper). Impurities in crude copper such as iron and zinc, which are more active than copper, are dissolved into ions (Zn and Fe) along with copper. Since these ions are not easily precipitated compared to copper ions, electrolysis can be avoided by adjusting the potential difference to avoid precipitation of these ions on the anode. Impurities that are less reactive than copper, such as gold and silver, are deposited at the bottom of the electrolytic cell. The copper sheet produced in this way is called "electrolytic copper", which is of very high quality and can be used to make electrical products. What is deposited at the bottom of the electrolyzer is called "anode sludge", which is rich in gold and silver and is very valuable, and has a very high economic value when it is taken out and reprocessed. Electrolytic copper can be further processed to make very fine electrolytic copper powder.
Advantages of SUNY GROUP's new environmentally friendly copper electrolysis equipment:
1. The electrolyzed copper material can be directly put into the anode frame for electrolysis without smelting.
2. No unpleasant toxic gas is produced during the electrolysis process, and the air at the site is fresh.
3. The electrolytic solution uses water-soluble acid with low acid concentration, which is not directly harmful to human body and safe to operate. 4.
The cost of electrolyzing one ton of high purity copper sheet is only 900 RMB, which can achieve high production value with low energy consumption.
5. The whole set of copper electrolysis equipment is widely used, it can be used for waste copper-containing liquid, crushed copper powder, copper alloy particles, waste copper plating gold. Silver. Nickel and other product scrap, really realize a machine multi-purpose.
