Slag Reduction Kinetics of a Lead Slag from a Secondary Lead Smelter
In both primary and secondary lead smelters, significant quantities of lead are discharged into the environment each year. Without the use of a settling (or zinc fuming) furnace, slag is discharged from the smelter containing between 0.5 and 3 wt% Pb [].This results in a smelter discharging significant quantities of lead into the surrounds each year.
