General Nickel Sulfate Recovery Process from Waste Batteries

The nickel sulfate solution obtained after extraction and back-extraction may still contain a small amount of impurities, which need to be further refined and purified. Commonly used refining methods include precipitation method, ion exchange method and so on. For example, by adjusting the pH of the solution, the impurity ions can be precipitated and removed to obtain a high pu...
