An economic and effective strategy synchronously utilizing blast furnace bag dust (BF-BD) converter-removing (C-RD) by carbothermic reduction roasting is reported to achieve separation recovery of iron zinc. In this paper, the effect operating parameters on rate remove Fe Zn from BD GD was initially studied synergetic reduction. The optimized include a temperature pf 1200 °C, time 90 min, FC/O ...

In the ironmaking processes via carbothermic reduction with tall-bed reactor, composite pellets are rapidly reduced to highly metallized direct iron (DRI) high productivity under temperature. Without coke making and ore sintering process, not only help broaden selection of raw materials but an environmentally friendly approach for process. this study, experiments were conducted ore-coal four he...
