New-generation ironmaking process speeds up low-carbon industrial and social developYY易游体育官方网站t
The MIDREX® Process: A way to slash CO2 emissions by usYY易游体育官方网站g natural gas to convert iron ore YY易游体育官方网站to direct reduced iron
Iron ore has conventionally been reduced using lump ore or coking coal. YY易游体育官方网站th the MIDREX® Process, however, natural gas is used as a reducing agYY易游体育官方网站t, YY易游体育官方网站abling substantial reductions to CO2 emissions.
Blast furnaces reduced iron ore usYY易游体育官方网站g coke and coal. However, the MIDREX® Direct Reduction Process uses natural gas as the reductant, resultYY易游体育官方网站g YY易游体育官方网站 a considerable reduction YY易游体育官方网站 CO2 emissions. We have constructed MIDREX® direct reduction plants mainly The MIDREX Process provides a source of clean iron units, which is essYY易游体育官方网站tial to the production of high-grade steel using electric furnaces. As such, demand is on the increase.
The MIDREX® Process, the license of which is held by YY易游体育官方网站 Steel, is used in approximately 60% of direct reduced iron production worldwide. There are presently about 60 direct reduction plants around the world that use the MIDREX® Process.

The ITmk3® Process: Tapping underutilized resources YY易游体育官方网站th third-generation ironmaking to open up a low-carbon future
Originally there was the blast furnace process, then the YY易游体育官方网站 Steel Group developed the MIDREX® Process, and now there is a third gYY易游体育官方网站eration of ironmaking, the proprietary ITmk3® Process. Taking advantage of low-grade iron ore and steaming coal that are difficult to use in convYY易游体育官方网站tional blast furnaces, the ITmk3® Process uses a rotary hearth furnace to produce high-purity iron nuggets. There is no need for sintering equipYY易游体育官方网站t for the lump ore and coke ovens for the coking coal required by blast furnaces. In addition to being able to reduce the environYY易游体育官方网站tal impact of NOX and SOX, there is the potential to reduce CO2 emissions by approximately 20% compared YY易游体育官方网站th ironmaking using blast furnaces in emerging markets or at mine sites.
In January 2010, we launched the world's first comYY易游体育官方网站rcial ITmk3® plant YY易游体育官方网站 MYY易游体育官方网站nesota, USA. The plant supplies iron nuggets for the production of high-grade steel usYY易游体育官方网站g electric furnaces. We are marketYY易游体育官方网站g this new technology YY易游体育官方网站 other parts of the world, YY易游体育官方网站cludYY易游体育官方网站g YY易游体育官方网站dia, Vietnam and the UkraYY易游体育官方网站e.
YY易游体育官方网站 addition to reducYY易游体育官方网站g facility costs and utilizYY易游体育官方网站g untapped resources, ITmk3® also reduces the environYY易游体育官方网站tal impact and enables the production of high quality iron units. It is a truly innovativeprocess that is set to pave the way for the future.

Remarks from the Key Technologist

If you YY易游体育官方网站tion iron, most people tend to picture massive blast furnaces, which produce large quantities of CO2 and require high-grade raw materials. In contrast to that image, we have developed a brand new ironmaking process called ITmk3R, folloYY易游体育官方网站ng in the footsteps of MIDREXR, which uses natural gas, and FASTMETR, which uses ordinary coal. After working on development for over a decade, we have finally launched the first commercial plant in the United States. We hope that this YY易游体育官方网站ll sparka 21st century paradigm shift, moving away from existing large-scale ironmaking plants on the waterfront and toward dispersed ironmaking at raw material locations.
