Coal is something that we might have come across at least once in our lifetime. It is a common substance used in many homes and even in big industries. That being said, we will be studying about coal and some of its uses here. Coal is basically a combustible sedimentary rock usually occurring in parts known as coal beds or coal seams.get price
High cost of mining makes it very important from a profit standpoint to recover all of the low ash coal, both coarse and fines. With the present trend toward mechanization, more fines are produced in mining. In many operations it is no longer economical to discard these fines to waste even though ash contiminants render the fines unmarketable without additional cleaning. Water conservation, stream pollution and refuse storage are also factors which must be taken into consideration along with marketing requireme
