Reusing steel slag as an aggregate for road construction requires to characterize the leaching kinetics and metal releases. In this study, basic oxygen furnace (BOF) steel slag were subjected to batch leaching tests at liquid to solid ratios (L/S) of 10 and 100 over 30 days; the leachate chemistry being regularly sampled in time.
Press filtered high lead silver leaching residue can be directly charged into the side blowing furnace for smelting. Lead and valuable metal is reduced into metallic status and are enriched into lead bullion or copper matte for further recovery. Zinc reports into slag and then is charged into the secondary side blowing furnace for fuming.
