本文研究了氯化法和深共晶溶剂萃取-电沉积法直接从镍冰铜中提取铜镍合金。对选择性氯化工艺的反应机理以及焙烧温度、焙烧时间、氯化剂加入量等氯化工艺参数对氯化产物的影响进行了实验研究。结果表明，镍锍中的硫化物（Ni 3S 2和Cu 2S）在氯化过程中可转化为氯化物（NiCl 2和CuCl）和硫酸盐（Na 2Ni（SO 4）2和NiSO 4）。然后用氯化物-尿素低共熔溶剂浸出氯化产物中的铜和镍，镍和铜的浸出率分别可达40.24%和58.21%。最后，从浸出液中电沉积了Cu-Ni合金，并对电沉积层的形貌、相组成和耐蚀性进行了系统的研究。结果表明，选择性氯化和深共晶溶剂萃取-电沉积工艺是从复杂镍冰铜中提取Cu-Ni合金的有效方法。
Direct electrochemical extraction of Cu-Ni alloy from nickel matte through chlorination and deep eutectic solvent leaching-electrodeposition processes has been investigated in this work. The reaction mechanism of the selective chlorination process and the influences of chlorination parameters including roasting temperature, roasting time and chlorinating agent addition on the chlorinated products were investigated thermodynamically and experimentally. The result shows that the sulfides (Ni3S2and Cu2S) contained in nickel matte can convert into chlorides (NiCl2and CuCl) and sulfates (Na2Ni(SO4)2and NiSO4) during the chlorination process. ChCl-urea deep eutectic solvent was then used to leach Cu and Ni components from the chlorinated products, and the leaching rates of Ni and Cu can reach 40.24% and 58.21%, respectively. Finally, Cu-Ni alloy has been electrodeposited from the leached electrolyte, and the morphology, phase composition, and corrosion resistance of the electrodeposited Cu-Ni alloy were systematically investigated. It is suggested that the selective chlorination and deep eutectic solvent leaching-electrodeposition processes provide a promising strategy for the extraction of Cu-Ni alloy from complex nickel matte.
