A pyro-hydrometallurgical process is proposed in this study for the selective arsenic removal and Pb Sb recovery from lead softening slag, which incorporates NaOH roasting followed by water leaching, carbothermic reduction, HNO3 leaching as steps. Lead containing 63.9 wt% Pb, 17.7 Sb, 4.4 As, first roasted with at 400°C, room temperature. The effect of temperature dosage investigated regard to yield Sb. arsenic-free slag reduced carbon antimonial lead. reduction are optimized applying...
Recycling electric arc furnace dust (EAFD) is significant for environmental security and resource recovery. To realize the short-flow recovery high-value utilization of zinc iron from dust, an innovative synchronous smelting reduction technology was proposed to treat EAFD. In this study, promoting mechanism reaction kinetics Zn Fe EAFD by were investigated. The results indicated that volatilization turned out be a two-staged model, in which controlled nucleation growth CO bubbles boundary...
