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 ...

In very simple terms, the process of converting ROM coal into marketable products is called coal preparation. Levels of cleaning Coal preparation results in at least two product streams, the clean coal product and the reject. Generally, five levels of preparation can be identified, each being an incremental level of cleaning over the previous one:

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.
