ActiveCN103498169AImprove sulfur contentSulfur content can be controlledElectrolysis componentsPhotography auxillary processesElectrolysisVulcanization
The invention discloses a preparation method for reducing sulfur impurities in electrolytic nickel, belonging to the technical field of wet-process metallurgy. The preparation method comprises the following steps of casting nickel matte into an anode plate, and putting the anode plate in an electrolytic bath to perform vulcanization so as to directly electrolyze a nickel anode; taking a nickel starting sheet produced in a starting sheet cell as a cathode, and putting the cathode into a diaphragm bag; putting purified electrolyte into a cathode chamber, wherein the liquid level of the cathode chamber is higher than that of an anode chamber to ensure that an anode liquid can not enter the cathode chamber; electrifying in the electrolytic bath to generate electrolytic nickel; purifying the anode liquid, namely performing four-stage purification including copper removal through extraction, iron removal through oxidation neutralization, cobalt removal through extraction and sulfur reduction. The sulfur impurities in the electrolytic nickel generated through normal electrolysis is less than 0.001%, and the average content of the sulfur impurities is 0.0005%. According to the preparation method disclosed by the invention, a normal soluble anode is used as a template, and the content of the sulfur impurities in an electrolytic nickel plate is reduced by reducing the sulfur content in the cathode liquid, so that an electrolytic nickel finished product with extremely low content of the sulfur impurities is obtained. The process method is simple, and can effectively control the content of the sulfur impurities in the electrolytic nickel, and the obtained high-quality electrolytic nickel finished product can be widely applied.
