Factors influencing base metal recovery from waste reverberatory furnace slags in a 50 kVA laboratory DC plasma arc furnace (2004)The recovery of cobalt and copper from waste slag was studied in a plasma DC-arc furnace in reducing conditions. Three fluxes, CaO, CaF2, and TiO2, were investigated for their influence on selective recovery of cobalt into ...
