Coal Beneficiation Coal beneficiation is a process by which the quality of raw coal is improved by either reducing the extraneous matter that gets extracted along with the mined coal or reducing the associated ash or both. Two basic processes of beneficiation: – Dry-deshaling: Non-coal or shaly-coal is removed without using any liquid media.

However, due to specific mineralogical characteristics (varies significantly with deposit), beneficiation process may differ for different type of deposits. Several techniques, such as wet-scrubbing, jigging, magnetic separation, gravity concentration, froth-flotation, selective flocculation, etc. are used to enhance the Fe content and reduce ...
The process requires little if any pre-treatment of the material other than grinding and operates at high capacity – up to 40 tonnes per hour by a compact machine. Energy consumption is low, approximately 1 kWh/tonnes of material processed. Since the only potential emission of the process is dust, permitting is typically relatively easy.
