direct reduction: FeO + C = Fe + CO indirect reduction FeO + CO = Fe + CO2 I don''t think that is what the terminology ''direct reduction'' means in this context. For a start most
Reducing the carbon intensity of the iron making value …
9/8/2020· "The majority of the work and the carbon-intensity is in the steel making process at the other end of the chain in Asia, for example in China, Japan and South Korea," he said. "It''s difficult for us to influence what goes on there and the energy used is significantly higher in the smelting process than it is in the mining process."
Direct reduction of iron | SpringerLink
In the blast-furnace process, direct reduction — in contrast to indirect reduction — means the reduction of ferrous oxide by carbon with the formation of CO. The terms “direct reduction of iron,” “direct production of iron,” “cokeless metallurgy,” or “non-blast-furnace metallurgy” are used in the literature to denote new methods for the metallurgical conversion of iron ore

Sulphur removal in ironmaking and oxygen steelmaking
Iron ore contains typically 0.01% sulphur and is only a minor source of sulphur in the steelmaking process [2,8]. In the BF-BOF process there are four process steps where sulphur can be removed:. BF;. HM pretreatment;. converter;. SM ladle treatment.
HIsarna ironmaking process - Wikipedia
The HIsarna ironmaking process is a direct reduced iron process for iron making in which iron ore is processed almost directly into liquid iron or hot metal. The process coines two process units, the Cyclone Converter Furnace (CCF) for ore melting and pre-reduction and a Smelting Reduction Vessel (SRV) where the final reduction stage to liquid iron takes place.

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.
Direct Reduced Iron (DRI) - UK P&I
Chapter 11 Direct Reduced Iron (DRI) 87 11.2 Cold-Moulded DRICold-moulded DRI is manufactured in the form of pellets (spheres) about 1 cm in diameter. These are produced from iron ore (principally iron oxide) which is crushed, partially freed from foreign material
Sponge Iron Production By Direct Reduction Of Iron …
This book provides a fascinating study of the very important emerging field of direct reduction in which iron ore is ‘directly reduced’ in the solid-state, using either natural gas or non-coking coal, to produce a highly metallised material, referred to as sponge iron (or
The Ironmaking Process | New Zealand Steel
The success of this direct reduction process of ironsands on a commercial scale was a hard-fought technological battle, culminating in a world first achievement for New Zealand Steel. At the Waikato North Head mine, the ironsand is concentrated by magnetic and gravity separation processes to increase the iron content and decrease the amount of loose impurities.
