  • Removal Of Ferric Iron As Hematite At Atmospheric

    Removal Of Ferric Iron As Hematite At Atmospheric

    Hematite was reduced to metallic iron following the route of Fe 2 O 3 –Fe 3 O 4 –FeO–Fe in reduction process, 14) and then the metallic iron was recovered by grinding followed by magnetic separation, so the recovery of iron depends on the metallization ratio of hematite. Reduction of iron oxides in a direct reduction system has been known.Fig. 7 shows the effect of roasting time on the iron grade and recovery rate. It can be seen that with the extension of roasting time, the iron grade and recovery rate continued to increase due to the gradual transformation of hematite into magnetite until reaching a peak roasting time of 25 min, after which it sharply decreased.

    Aug 15, 2020 The furnace is filled at the top with the iron ore oxide most commonly hematite (\(Fe_2O_3\)) but can also magnetite (\(Fe_3O_4\)), carbon called coke and limestone (\(CaCO_3\)). For the purpose of this discussion the iron ore oxide hematite (\(Fe_2O_3\)) will be shown. On a side note, Hematite gets its name from the Greek word meaning blood.The common iron ores include magnetite, hematite, limonite and siderite. Among them, as typical refractory iron ore, limonite has the characteristics of easy to sliming, poor separation index, etc, but it still is a favorable backing to solve the shortage of iron mineral resources due to its abundant reserves.
