Abstract :
The dry beneficiation of three types of Slovakian brown coal, namely Ciʹgel, Handlovaʹ, and Novaʹky coal was conducted via triboelectrostatic separation. Three different types of separators—parallel plate, cylindrical and louvered plate—were used for this study. It was found that a parallel plate separator could reduce the ash contents of Ciʹgel and Handlovaʹ coals. The poor quality of separation for the Novaʹky coal studied is probably due to the particle–particle interactions and surface oxidation states of the coal.
