of heavy metals. In this study, coal-based direct reduction followed by magnetic separation was presented to separate Pb, Zn, and Fe from lead slag. Lead slag was mixed with coal and additive and treated in a laboratory tube furnace. In the process of direct reduction, Pb
The more advanced way to smelt iron is in a blast furnace. A blast furnace is charged with iron ore, charcoal or coke (coke is charcoal made from coal) and limestone (CaCO 3 ). Huge quantities of air blast in at the bottom of the furnace, and the calcium in the limestone combines with the silicates to form slag.
