Generally, a waste copper material is dissolved in dilute sulfuric acid to which an oxidizing agent (for example, a 10% hydrogen peroxide solution) is added, and then impurities such as iron are recrystallized and purified, and a large amount of basic copper sulfate having a high purity can be obtained. The Basic Copper Sulphate used in the laboratory is generally commercially available, and it can also be purified by dissolving the waste copper compound in sulfuric acid.
Electrolyte recovery method Waste electrolyte (containing Cu50～60g/L, H2SO4180～200g/L) is reacted with calcined copper mud to make fine copper powder. After separation and sedimentation of the reaction solution, the supernatant is cooled, crystallized, separated and dried. , the preparation of basic copper sulfate.
