Comparison of the Projected Results of Coarse Thermal Coal Cleaning in Various Gravity Separation Apparatuses

Abstract:

Gravity separation is considered as the most used processing technique for thermal coal cleaning. A broad variety of methods and machines was developed for that purpose. However, the performance of those apparatus under different conditions is not the same. In this article, the results of coarse thermal coal cleaning in various equipment were simulated by means of mathematical modelling. The comparison of obtained quantitative and qualitative indicators of gravity separation showed that for processing of difficult-to-wash thermal coal the heavy medium-based processes are more favorable, whereas for more easily washable coal jigging can be efficiently used as well.
