Description
A lot of coal fines are generated during the crushing, screening and washing processes. Currently, it is difficult to successfully recover these coal fines. Conventional gravity processes generally have poor efficiencies in treating coal less than 1mm. The centrifugal separators have been proved to be the better route for processing these coal fines (Uslu, Sahinoglu and Yavuz, 2012). The study herein focused on the upgrading of coal with the aid of a Knelson concentrator (KC) specifically the deashing of coal fines (-1 mm size fraction). The experiments were conducted at the University of Pretoria with a laboratory KC-MD3 batch type Knelson concentrator.
