Coal is slightly denser than water (1.0 megagram per cubic metre) and significantly less dense than most rock and mineral matter (e.g., shale has a density of about 2.7 megagrams per cubic metre and pyrite of 5.0 megagrams per cubic metre). Density differences make it possible to improve the quality of a coal by removing most of the rock matter

Coal is a sedimentary rock that is blackish or brownish-black in colour and is developed from start rock also referred to as coal seams. This is assumed to have developed from the residue of the algae plants. Coal is composed of a maximum amount of carbon with other organic elements chiefly hydrogen followed by sulphur, oxygen, and nitrogen.
