Possible Prospects of Using Muko Iron Ore for Iron Production. Natural iron ores are used for iron making through the blast furnace (BF) process and direct reduction (DR) or direct smelting reduction (DSR) processes. The major routes for application of natural iron ores are schematically illustrated in Figure 6.

Whereas more than 90% of the global DRI plants use (lower grade) natural gas, production in India is primarily coal based. The energy consumption in natural gas based DRI production is well known and established to be 10.4 GJ/t-DRI.
Midrex Process for Direct Reduction of Iron Ore.,Midrex Process for Direct Reduction of Iron Ore.,by using CO2 for reforming, less natural gas is,Direct Reduction Of Iron Ore Using Natural Gas,Direct Reduction Iron (DRI) furnaces are used to produce iron from iron ore oxides using natural gas. The furnace takes the iron ore in the form of sphericDirect reduced iron - Wikipedia,In both cases, the objective of the process is to drive off the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1200 °C). The direct reduction process is comparatively energy efficient.
