Coal preparation is the removal of undesirable material from the RunofMine (ROM) coal by employing separation processes which are able to differentiate between the physical and surface properties of the coal and the impurities. Through coal preparation, a uniform product is achieved. Washability Study
7. 7 2. Box cut Box cut is the initial/first cut given for the physical development of a mine. The name 'Box cut' has been attributed to this cut as this cut generally looks like a top open box having an inclined floor and walls on three sides (front wall and two side walls) in case of opening up of subsurface deposits.
7. Coal beneficiation is the process of removal of the contaminants and the lower grade coal to achieve a product quality which is suitable to the application of the end user either as an energy source or as a reducing agent for metallurgical extraction of iron ores. A common term for this process is coal "washing" or "cleaning". Coal Processing forms a link between coal mining and coal ...
2. ACTIVATED CARBON Activated carbon is a form of carbon which could be produced from any carbonaceous material such as coal, rice husk, paddy husk, coconut shell, wood etc. Due to their low ash content, high carbon content and natural pore structure, coconut shells are ideal for producing high quality activated carbon. Activated carbon manufactured from coconut shell is considered superior to ...
