Significance and influence of the paper ″Views on the Issues Relating to the Treatment of Coal Slurry Water″

An introduction is made to Professor Wang Zuna′s paper ″Views on Issues Relating to the Treatment of Coal Slurry Water″, with the focus centered on the coal slurry circulation coefficient mathematical model derived, as well as the model-based comparative analysis of the different basic flowsheets of the coal slurry water treatment processes made by the author of the published paper. The model derived provides a technical basis for promoting the application of direct flotation process, and the inspiration to operate the thickener with less intensive thickening effect and large underflow volume. The prime examples are cited to illustrate the way to tackle the problems encountered in field operation by applying the different slime circulation coefficient mathematical models developed according to the method proposed by the author of the abovementioned paper.
