【摘要】 针对临江式铁锰矿石展开了铁矿物深度还原的热力学和动力学研究,结果表明铁氧化物的深度还原过程是按照Fe₂O₃/FeCO₃→Fe₃O₄→FeO→Fe的顺序进行;铁颗粒的生长过程可分为还原成核、深度还原、铁颗粒长大三个阶段。在此基础上,进行了临江式铁锰矿石深度还原一高效分选试验研究,并获得了全铁品位为88.09%,金属化率为86.81%,铁回收率为88.32%的深度还原铁粉产品。此深度还原铁粉产品可直接作为炼钢的原料使用。更多还原

【Abstract】 Thermodynamics and kinetics for deep reduction of iron mineral from Linjiang ferro - manganese ore were investigated.The deep reduction of iron mineral was in order of Fe₂O₃/FeCO₃→Fe₂O₃→FeO→Fe.The grain growth of iron phase could be divided into three stages,nucleation stage,the deep reduction stage and particle coarsening stage.At the same time,the deep reduction and separation for Linjang ferro - manganese ore was conducted to obtain the iron products with iron grade 88.09%,iron recovery 88.32%and metallization rate 86.81%.The iron products can be used as raw feed for steel.更多还原
