    SOUTH AFRICAN COAL SECTOR REPORT

    Coal is a combustible sedimentary rock formed from vegetation that has been consolidated between other rock strata and altered by the combined effects of pressure and heat over millions of years. Coal is composed primarily of carbon, and also contains varying amounts of other components, like hydrogen, oxygen, sulphur and other impurities.
