Coal Beneficiation Technology

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

What is Coal Washing?

Coal washing is a process that is undertaken in a coal washery or coal preparation plant (CPP) where coal is refined or cleaned of impurities Coal washing involves using water mechanical techniques and relies on gravity and the difference of density between coal and it's impurities which are usually more densely packed due to the fact that

Coal Preparation

Coal preparation process starts with crushing and screening of freshly mined coal which removes some of the non-coal material Washing is actually the process of separation of non-coal materials Washing or cleaning of coal represents the most important step of coal preparation Coal is washed in order to decrease the ash content and thus producing three different streams of products clean coal
