Direct Reduction Process an overview ScienceDirect
The direct reduction processes in combination with the melting of directly reduced iron to produce steel in the EAF offer an alternative to the BF-BOF route. The basis of the direct reduction process is that solid sponge iron is produced by removing oxygen from the ore in a shaft furnace, rotary kiln furnace or fluidised bed. Sponge iron can be

Direct Reduction Process Description
Process Description R&D Trends. In a direct reduction process, lump iron oxide pellets and/or lump iron ore, are reduced (oxygen removed) by a reducing gas, producing direct reduced iron (DRI). If the cooling stage is omitted, the DRI can be immediately briquetted into hot briquetted iron (HBI).
Direct Reduced Iron Midrex Technologies, Inc.
2021-2-28 Regardless of the steelmaking route, there is a form of direct reduced iron (DRI) for every application. DRI is a premium ore-based metallic (OBM) raw material made by removing chemically-bound oxygen from iron oxide pellets and lump ores without melting.
Direct Reduction Plant Products || KOBE STEEL, LTD.
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
Resources Trend and Use of Direct Reduced Iron in
2015-1-27 Direct reduction is a process for reducing iron ore in the solid state. It requires much less capital investment than the BF process and requires no coke. Therefore, DR plants have nbeen built mainly in oil and natural gas producing countries to supply raw iron for EAF processes. Particularly in the

Steel making experience in the use of Nigerian Iron
The production of steel from the locally available Itakpe Iron Ore in Nigeria was achieved in the Delta Steel Direct Reduction-Electric Arc Furnace Plant. The ore was originally thought to be unsuitable for use in the direct reduction process due to its low total iron content, less than 64% and high gangue content which was in excess of 4% and above the maximum acceptable limit of 3.5%.
Upgrading Nigerian iron ores SpringerLink
A number of Nigerian iron ore deposits have been upgraded to the specifications of concentrates for the blast furnace and the direct reduction iron- and steel-making plants. Depending on the mineralogy of the ore deposits, the techniques of oil agglomeration, magnetizing reduction, washing and scrubbing, gravity concentration, and reverse froth flotation have been utilized.

2009-2-1 Ironmaking involves the separation of iron ores. It not only represents the first step in steelmaking but also is the most capital-intensive and energy-intensive process in the production of steel. The main route for producing iron for steelmaking is to use the blast furnace, which uses metallurgical coke as the reductant. Concerns over the limited resources, the high cost of coking coals, and
