iron by a suspension reduction technology that uses hydrogen as the reducing agent and fine iron oxide concentrates in a suspension reduction process, with the ultimate objective of eliminating or drastically reducing the generation of CO2 in the steel industry.
The chemistry of steelmaking. The big picture.
Most workable iron ores are rich in iron (III) oxide, Fe 2 O 3. Making iron by removing oxygen from the ore is the first step in the manufacture of steel. Reduction and oxidation Removing oxygen chemically from a substance is called reduction. The industrial
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.
Hydrogen as a Clean Alternative in the Iron and Steel …
2019/11/25· 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).
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.

Sponge Iron Manufacturer India
Many ores are suitable for direct reduction. Direct reduction processes can be divided roughly into two egories: gas-based, and coal-based. 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
