Application of DY984N Copper Extractant, DY319 Nickel-Cobalt Co-extractant, and DY272 Cobalt Extractant in Copper-Nickel-Cobalt Wet Extraction

Introduction:
Copper-nickel-cobalt wet extraction is a crucial metallurgical technique used to extract copper, nickel, and cobalt from sources such as nickel sulfides, copper-cobalt ores, and cobalt residues. This article aims to discuss the sulfurized nickel electrolysis technique, selective leaching of high-nickel matte, pyrometallurgical and hydrometallurgical techniques for nickel oxide ores, as well as the application of DY984N copper extractant, DY319 nickel-cobalt co-extractant, and DY272 cobalt extractant in these processes.
Body:
Sulfurized Nickel Electrolysis Technique:
Sulfurized nickel electrolysis involves placing sulfurized nickel anodes and nickel plates (with a diaphragm) into an electrolytic cell, where nickel ions deposit on the cathode under the influence of direct current. To prevent impurities from depositing on the cathode, a diaphragm is used, and the anolyte must undergo purification to remove impurities, obtaining a purified electrolyte (catholyte) for recycling. During the anolyte purification process, DY272 cobalt extractant can be utilized for chlorine gas oxidation to remove cobalt.
Selective Leaching of High-Nickel Matte:
Selective leaching of high-nickel matte involves wet ball milling water-quenched high-nickel matte, followed by selective leaching with sulfuric acid. DY984N copper extractant can be employed to remove copper impurities from the leachate, obtaining a purified nickel sulfate solution.
Hydrometallurgical Technique for Nickel Oxide Ores:
The hydrometallurgical technique for nickel oxide ores involves pressure acid leaching and atmospheric acid leaching. Pressure acid leaching is suitable for ores with high iron content and low magnesium content, achieving nickel and cobalt leaching rates above 95%. DY272 cobalt extractant can be used for cobalt extraction from the leachate.
Cobalt Extraction from Cobalt Sulfide Concentrate:
Extracting cobalt from cobalt sulfide concentrate (containing cobaltite) is typically done through a sulfate system, where the concentrate is roasted, leached, and purified to obtain cathode cobalt or other cobalt salt products. DY272 cobalt extractant can be used for cobalt extraction from cobalt sulfide concentrate.
Cobalt Extraction from Copper-Cobalt Ores:
The process for extracting cobalt from copper-cobalt ores is similar to the treatment of cobalt sulfide concentrate. DY319 nickel-cobalt co-extractant can be employed to dissolve copper and cobalt metals in the leachate.
Cobalt Recovery from Cobalt Slag in Nickel Electrowinning Process:
Cobalt slag obtained during the nickel electrowinning process contains cobalt in the form of high-valence oxides, appearing as black, mud-like material. DY272 cobalt extractant can be used for cobalt extraction into the organic phase, facilitating cobalt recovery.
Conclusion:
Copper-nickel-cobalt wet extraction is a significant metallurgical technique for extracting copper, nickel, and cobalt from various sources. The application of DY984N copper extractant, DY319 nickel-cobalt co-extractant, and DY272 cobalt extractant plays a vital role in improving the efficiency and purity of the processes discussed. These products contribute to the advancement of copper-nickel-cobalt wet extraction technology.
