two process used to reduce iron oar to iron

Li et al. [28] used the FFC to directly reduce iron oxide to iron electrochemically. The process can produce two useful products at the cathode and anode, providing a zero emission technology for the steel smelting industry. However, at present, FFC process still needs a relatively pure iron oxide raw material, the electronegative metal than

In contrast to the blast furnace process, the direct-reduced iron process operates at temperatures of up to 1000 °C. The iron ores are therefore not melted! This also applies to the gangue contained in the ore, which is why the iron ores used must be relatively low in gangue from the outset. The reduction gases only dissolve oxygen from …
