摘要
分析了中国煤炭资源现状及炼焦煤中煤产品的使用情况,提出了中煤再选的必要性,并以山西焦煤集团炼焦煤选煤厂生产的副产品中煤为例,提出了物理方法分选的局限性,对化学方法脱灰的可行性进行了研究,并对工业化前景进行了分析。
Analyzes the current situation of China′ s coal resources and the use of coal products in coking coal, puts forward the necessity of coal re separation, and takes the by-product middle coal produced by coking coal preparation plant of Shanxi coking coal group as an example, puts forward the limitations of physical method separation, studies the feasibility of chemical method deashing, and analyzes the prospect of industrialization.
