金川/酒钢冶炼渣综合利用的新概念与物理化学*

.The most of metal ore sources in China are low-grade and intergrowth. Therefore, it is extremely important for us to develop some kinds of comprehensive technology for metallurgy, which not only benefit to source utilization but also to environment protection. The project of study of comprehensive utilization of Jinchuan and Jiuquan slag is aimed at this goal. In this project, some ironmaking and steelmaking methods based on Jinchuan and Jiuquan slag have been developed that can recover over 92 percent iron and other metals such as Ni, Co and Cu, some Sialon materials and cement have been made by using metallurgical slag. Also, in this project some new technologies for extractive metallurgy were also examined and the results are very encouraging. Besides, some fundamental researches have also been done accompanying this project. We are pleased to announce that some new models have been developed that can be used to calculate both thermodynamic properties and kinetic properties such as surface tension, viscosity, density and conductivity…and so forth especially for metallurgical slag including both homogeneous or partial homogeneous systems.

研究我国冶金二次资源综合利用中若干冶金物化理论问题：冶金二次资源熔体（废钢、炉渣、闪速熔炼渣）物化性质的模型估算；有价组元分离的新方法、新工艺；提取有价元素后废渣利用的可行性。在此基础上，初步建立冶金物化理论新体系，发展新模型和研制新软件，为冶金二次资源的再利用和冶金工业的可持续发展奠定理论基础，并提供数据和实用软件。.
