What are the types of coal? US Geological Survey
There are four major types (or “ranks”) of coal Rank refers to steps in a slow, natural process called “coalification,” during which buried plant matter changes into an ever denser, drier, more carbonrich, and harder material The four ranks are:Anthracite: The highest rank of coal It is a hard, brittle, and black lustrous coal, often referred to as hard coal, containing a high Ray et al (1951a,b) determined the effect of coal mine dust and supplemented quartz (2–40%) in rats after intratracheal doses of 100 mg of each dust They observed fibrotic lesions and concluded that anthracite coal mine dust had no inhibitory action on quartzinduced fibrosisSilica, Some Silicates, Coal Dust and paraAramid FibrilsIndiana Center for Coal Technology Research 5 ANTHRACITE COAL Anthracite: Sometimes also called “hard coal,” anthracite forms from bituminous coal when great pressures developed in folded rock strata during the creation of mountain ranges This occurs only in limited geographic areas –primarily the Appalachian region of Pennsylvania COAL CHARACTERISTICS Purdue University17 Lignite Combustion 171 General15 Coal is a complex combination of organic matter and inorganic ash formed over eons from successive layers of fallen vegetation Coals are classified by rank according to their progressive alteration in the natural metamorphosis from lignite to anthracite Coal rank depends on the volatile17 Lignite Combustion US Environmental Protection Agency
