The strict requirement currently placed in the coal industry to improve and maintain a high and consistent quality of fuel has meant that fine high ash material can no longer be included as part of the final washed coal product. Improvements and changes in underground mining techniques have added to the problem of fines, with the quantity of mineral of size less than 0.5 mm reaching the coal preparation plant regularly being in the order of 15-20%.

The aim of this project was to examine the possible ways in which the product handleability of power station fuel could be improved by changing the nature of the fine portion of the blend. Three independent research projects were undertaken in order to study aspects of moisture and slimes removal. The projects concerned were: the assessment and evaluation of a fine-coal de-watering centrifuge; improved de-watering by the application of electrophoretic techniques; examination of developing flotation techniques. The results of the projects are presented in this report. .
