Reduction method of hematite

机译:赤铁矿的还原方法

摘要

The present invention comprises the steps of preparing raw pellets by mixing hematite (Fe 2 O 3 ) with water (H 2 O), drying the raw pellets to remove moisture, dried raw pellets, coal and comprising the step of causing the hematite (Fe 2 O 3) a reduction reaction by heating the mixture of step and the dried raw pellets, the coal and the calcium carbonate (CaCO 3) of mixing a calcium carbonate (CaCO 3), wherein by a reduction reaction is reduced to the hematite (Fe 2 O 3) is at least one selected from the group consisting of FeO and Fe 3 O 4 iron oxide, tight the hematite according to the above reduction reaction yirueojim (Fe 2 O 3) It relates to a method for reducing hematite, characterized in that the sulfur (Sulfur) component contained in the reduction. According to the present invention, desulfurization and reduction may be possible at the same time.
