Abundance and forms of sulfur in coal The sulfur content in coals varies considerably but is most commonly within the range of % to 5% total sulfur. The coal with less than 1% sulfur is classified as low-sulfur coal. Coal with 1% to < 3% sulfur is medium-sulfur coal. Coal with ≥ 3% sulfur is high-sulfur coal.

Coal is slightly denser than water ( megagram per cubic metre) and significantly less dense than most rock and mineral matter (, shale has a density of about megagrams per cubic metre and pyrite of megagrams per cubic metre).
