Abstract
The process is based on the recovery of zinc, lead and iron present in the dust of electric arc steelworks. Zinc is recovered by carbothermic reduction of the dusts, pelletised together with coke, limestone and bentonite, in a retort type furnace with condensation of the zinc, while iron and lead are recovered by melting the reduced pellets. This process applies to the heating gas of a treatment furnace or the preheating of a charge.
