A lead oxide ball mill, or grey oxide plant (as it is generally called in lead trade), is a basic processing device in metallurgy. for lead processing, we provide dry type, semi-autogenous mills. once charged from one end, the rotation of the drum and friction of pellets raise the temperature to lead to reaction of lead with oxygen and.
A simple fusion of the lead in an electric induction furnace is sufficient. superdesulphurization of the battery paste the heart of the stc process is the conversion of the paste from paste sulphate to pure lead oxide. this process takes place in a two stadium reaction. ball mill reactors are used in order to remove nearly completely the lead.
Alternatively, mixed lead oxides recovered from battery lead oxide pastes are mixed with carbon and smelted directly in a furnace to make molten lead. then the resulting lead in ingot form is shipped to a plant which has a barton reactor or ball mill process to be oxidized to the leady lead.
