WebAug 22, 2024 · In electrorefining, nickel dissolves and is removed in the electrolyte purification circuit. Some of the nickel ends in anode slime. Pb, Zn, and Sn are rejected in slag or offgas, especially in bath smelting, and in converting, less than 10% of these end up in blister copper. Pb can also be removed in the anode furnace by using silica flux. http://chemistry.elmhurst.edu/vchembook/336electrorefine.html
