It is easily separated Co from graphite by magnetic separation. The product of electrolysis under suitable conditions was Co which facilitated the magnetic separation of the metal from the graphite. The remaining product of magnetic separation after electrolysis at 1.5 V-0.1 h is cobalt oxide and graphite (Figure 3 A).
Among them, water electrolysis has the highest separation factor, therefore, it plays a crucial role in the final separation stage. It is, therefore, very important to develop a cathode material having a high separation factor. In the practical electrolysis plant, mild steel has been employed as a cathode material for deuterium separation.
Lead, zinc, and iron were recovered from jarosite residues using direct reduction followed by magnetic separation. The influence of the coal dosage, reduction temperature, and reduction time on the volatilization rates of lead and zinc and the metallization rate of iron were investigated.
