Name the common elements present in the anode mud in electrolytic …
Hint: The impurities that are present in the copper we take for refining may get deposited in the form of anodic mud. Only the ions that are less basic than copper and are present in the solution can be found in the anodic mud. Complete answer: The commonly present elements in the anodic mud in electrolytic refining of copper are …
Lead processing
Lead processing - Refining, Smelting, Alloying: To remove and recover remaining impurities from lead bullion, either pyrometallurgical or electrolytic refining is used; the choice between the two methods is dictated by the amount of bismuth that must be eliminated from the bullion and by the availability and cost of energy. The Parkes zinc …
Removing antimony from waste lead storage batteries alloy …
In the process of electrolytic refining, the required antimony content of lead anode plate is approximately 0.4–0.7 wt%. When antimony content of lead anode plate is more than 1.2 wt%, antimony firmly adheres to the residual lead anode plate during the refining process, which leads to difficulty in cleaning.
