Physical and chemical coal cleaning AIP Conference Classification of Coal Engineering ToolBox

Coal is cleaned industrially by freeing the occluded mineral impurities and physically separating the coal and refuse particles on the basis of differences in density settling characteristics or surface properti While physical methods are very effective and low in cost when applied to the separation of coarse particles they are much less effective when applied to the separation of fine After a continuous process of burial and alteration chemical and physical changes occur until the coal is classified as bituminous dark and hard coal Bituminous coal ignites easily and burns long with a relatively long flame If improperly fired bituminous coal is characterized with excess smoke and soot

Coal Structure and properties of coal BritannicaCarbon C Chemical properties Health and Environmental

Coal Coal Structure and properties of coal The plant material from which coal is derived is composed of a complex mixture of organic compounds including cellulose lignin fats waxes and tannins As peat formation and coalification proceed these compounds which have more or less open structures are broken down and new compounds—primarily aromatic benzenelike and hydroaromatic Carbon and its components are widely distributed in nature The estimation is that carbon forms 0 032 of The Earth’s crust Free carbon is found in big reservoirs like hard coal amorphous form of the element with other complex compounds of carbon hydrogen nitrogen Pure crystalline carbon is found in the form of graphite and diamond
