COARSE DRY COAL CLEANING R. Q. Honaker University of Kentucky Department of Mining Engineering Lexington, Kentucky, USA 40506-0107 Workshop on Coal Beneficiation and Utilization of Rejects : Initiatives, Policies and Best Practices Ranchi, India August 22 – 24, 2007
research on dry coal beneficiation methods to avoid reliance on the conventional wet processing methods. Dry coal beneficiation with an air dense-medium fluidized bed is one of the dry coal processing methods that have proved to be efficient. In this study a (40 x 40x 60) cm dry batch air fluidized bed coal separator with a relatively
A Comparison of Coal Beneficiation Methods Abstract Although iron pyrites and other minerals are removed from coal on an industrial scale almost exclusively by gravity separation methods at the present time, other beneficiation methods are coming into use. Among the

Dry beneficiation is an alternative approach. The present work is a review and critical assessment of topics relevant to dry processing of coal, comprising comminution, size classification, characterisation and analysis, sorting at coarse sizes, mechanical beneficiation according to density at medium sizes, and electrical and magnetic ...
This report reviews a broad range of technical developments in coal beneficiation covering conventional, physical dense-media and dry coal treatment, upgrading technologies using thermal, chemical and bio-oxidation, coal blending, and applications for the use of ultrafine coal and waste streams.
Dry coal beneficiation with sorting systems; wet drum magnetic separators for traditional processing (de-stoning for greater efficiency) Even today, traditional coal beneficiation is performed using coal washing with large amounts of water. It is then necessary to expend considerable energy drying the coal …

The wet beneficiation process for coal cleaning is currently the predominant method of purification of coal in the world. However, dry beneficiation of coal has obvious advantages over wet processes. The dry processes for coal are based on the physical properties of coal and its associated mineral matters.
Dry coal beneficiation has an inherent advantage since it uses no process water and reduces the costs that are associated with process water, fines dewatering and slurry confinement. In particular, dry coal beneficiation is more suitable for coal cleaning in dry regions that lack available processing water.
