我国炼焦煤洗选工艺现状与展望

State-of-the-art and development prospect of China's coking coal cleaning technology

介绍了我国炼焦煤资源及其洗选加工现状,对炼焦煤主流洗选工艺中的主洗环节、粗煤泥分选环节与煤泥浮选环节进行了详细分析,提出了工艺设计原则,并对炼焦煤洗选工艺的发展趋势进行了阐述。

Following an introduction to Chinag reserves of coking coal resources and the present status of the technological processes for preparation of such coal, the paper presents an in-depth analysis of the primary processes applied in coking coal main-stream washing processes, as well as the coarse slime sep- aration processes and fine coal flotation processes. The criteria for the design of coking coal washing processes are proposed. At the end of the paper, the author elaborates on the developing trend of coking coal washing technologies.
