Ore Dressing Iron Making Process

Direct reduced iron DRI process In addition to the process route via the blast furnace process there is another option for extracting crude steel from iron ores using the so called direct reduced iron DRI process secondary route The starting point for the efforts to find an alternative to the blast furnace process was the relatively high process expenditure.
