Recycling direct-reduced iron produced by rotary hearth furnace in the blast furnace has the effect of reducing the reducing agents consumption, such as coke. The zinc removed within the rotary hearth furnace can also be recovered as crude zinc oxide at a waste gas processing facility, allowing it to be sold as a high-grade raw material for zinc refining.

The iron and steel production processes are characterized by a considerable environmental impact. The reduction of this impact, in particular emissions, is the target of modem
Blast furnace process - tec-science
In the indirect reduction zone, the iron oxide contained in the iron ores is reduced by carbon monoxide gas, whereby the iron ores are not melted! Direct reduction zone If the iron ores, which have not yet been reduced, move further down in the blast furnace, then the carbon can also directly reduce the iron oxides contained in the ore due to the high temperatures.

The Lion Group
Its newest addition, a Direct Reduced Iron (DRI) plant in Banting, using Midrex technology has a capacity of 1.70 million tonnes per annum. The increased supply of DRI will help to reduce the dependence on scrap as raw material for steel making by the Group’s various steel mills and enable the production of high quality steel.
The FINEX Process :: Total Materia Article
In the Finex process, iron ore fines are charged into a series of fluidized-bed reactors. The fines pass in a downward direction where they are heated and reduced to direct-reduced iron (DRI) by means of a reduction gas – derived from the gasifiion of the coal
Iron and Steel Emissions | Global Greenhouse Warming
Iron is the most abundant element by mass of our entire planet, making up 35% of the mass of the Earth as a whole. Steel is an alloy consisting mostly of iron, with a carbon content between 0.02% and 1.7 or 2.04% by weight (C:1000–10,8.67Fe), depending on grade.
Sponge Iron – Prakash Industries Limited
Sponge iron is a highly processed form of iron ore which contains metallic iron in the range of 83-88% obtained by direct reduction without melting it. Due to high porosity, the resulting iron is called sponge iron. It is used as a raw material for manufacturing steel
Hydrogen as a Clean Alternative in the Iron and Steel …
25/11/2019· Traditional iron ore reduction utilizes a chemical reaction between iron oxide and carbon monoxide sourced from heating coke fuel in a blast furnace. Coke is a hard, porous, nearly pure carbon product made by heating coal in the absence of air (in coke ovens).
