This conversion not only alleviates the problems with disposal but also converts a waste material into a high value-added marketable commodity.关键词:......
,Northeastern University, Shenyang 110819, China)Abstract:As valuable energy in iron- and steel-making process, by-product gas is widely used in heating and technical processes in steel plant. After being used according to the technical requirements, the surplus by-product gas is usually used for buffer boilers to produce steam. With the rapid development of energy conservation technology......
, solvent extraction and ion exchange adsorption. It is thought that recovery of scandium from red mud should be considered as a direct objective rather than a by-product in the development of overall......

Multi-stage Electrostatic Separation for Recovering of Aluminum from Fine Granules of Black Dross曹云霄,WANG Zhiqiang,WANG Jinjun,李国锋School of Electrical Engineering, Dalian University of Technology摘 要:Separation of aluminum from fine granules of black dross, which is a waste by-product in secondary aluminum production, was investigated. The separation......
of these solid wastes are the major concern in the world. Semi-coke generated in coal-based direct reduction process of iron ore is a by-product and its suitable utilization is not available so far. In order to handle it properly, the characteristics of this by-product were comprehensively investigated. A series of analysis methods were used to demonstrate its mineral compositions, petrography and physico......
