Upgrading of Coal With The Aid of a Knelson Concentrator
R1500,00
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.

A pilot brine concentrator treated Stage 3 reject effluent from a mine water reclamation plant, raising total dissolved solids from 24 g/L to 154 g/L at 88 per cent water recovery. The condensate met the national potable water specification. A separate run concentrated brine from 76 g/L to 145 g/L, solid salts were precipitated, and no scaling or fouling was seen.
