Rapid and direct magnetization of goethite ore roasted by biomass fuel

摘要: Biomass is a renewable and carbon neutral solid fuel. Utilization of biomass in iron ore roasting process as heating agent reducing contributes to energy conservation emission reduction, can partially replace for coal coke. The instead coke was mixed together with powder from the north Hainan province into ball investigate effects mixture composition, reduction temperature, reaction time, thermal magnetic properties mixture. results show that time dosage are correlated quality magnetism ore, within experimental conditions. mechanism weakly goethite stronger oxide has been discussed. ores dramatically reduced magnetized by about 20 wt.% at low temperature. Application prospective effective use decreasing consumption fossil fuels steelmaking process.
