    The main components of a rotary kiln are an inclined cylindrical, refractorylined reaction shaft equipped to rotate over rollers and a burner Process heat is generated by burning fine coke or coal contained in the charge and by the exothermic heat of the PbO reduction by CO This process produces molten lead and a slag with 3–5% Pb
