Optimization Of Microwave Carbothermal Reduction For


The carbothermal reduction involves roasting of the ore in a reducing environment at 500700 C resulting in a partial reduction of hematite to magnetite followed by application of lowintensity magnetic separation LIMS to produce ironrich magnetic product and tailings.

Direct Reduced Iron Wikipedia


Direct reduced iron DRI, also called sponge iron, is produced from the direct reduction of iron ore in the form of lumps, pellets, or fines to iron by a reducing gas or elemental carbon produced from natural gas or coal. Many ores are suitable for direct reduction.

Can Hydrogen Be Used Instead Of Carbon In The Smelting Of


Jan 14, 2016 Carbon is rapidly dissolved and reacts with oxygen from incoming iron ore to from carbon monoxide and iron. This reaction is endothermic and therefore to keep the process going additional heat has to be supplied .This is achieved by reacting carbon monoxide released from the bath with oxygen from top injection of air.
