Direct Reduction is an iron making process for the new era, which utilizes natural gas to reduce iron ore to produce Direct Reduced Iron (DRI). As Direct Reduction Plants are not built on the same, enormous scale as Blast Furnaces, their investment costs are lower, and they have been mainly constructed in developing countries where natural gas is relatively inexpensive.
