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.

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.
