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
