(2 ) Secondly,already in 2002 AM engaged in the development of breakthrough technologies to further drastically reduce the carbon intensity of steelmaking.After screening a large number of candidates a few were selected for further development.A first breakthrough technology which is the most advanced stage of development can be applied to existing blast furnace and is reaching maturity and a demonstration on industrial scale of this technology is under preparation.In itself this technology will decrease the dependency on carbon as well as increase the productivity of the original blast furnaces.Real big gains can be made if this technology can be combined with underground carbon storage. In the AM roadmap the impact of raw materials(DRI,scrap) was excluded.In the longer run however the attention will have to turn to the overall footprint of materials and the long term consequences of the choice of materials.Increasing the recovery while preserving the quality of used steel products will leverage greatly the efforts done in the production of primary and secondary steel and power.展开更多

A research project conducted by Baotou Shibo Rare Earth Extraction ＆ Equipment Co. Ltd., Baotou REE Research Institute, and Baotou Steel ＆ REE Group Hi-Tech Co. Ltd （Inner Mongolia）, has successfully solved the problem using a centrifugal extractor and advanced techniques to achieve a key breakthrough.展开更多
