Anthracite Mohs scale), its higher relative density of 1.3–1.4, and luster, which is often semi-metallic with a mildly brown reflection. It contains a high percentage of fixed carbon and a low percentage of volatile matter. It is also free from included soft or fibrous notches and does not soil the fingers when rubbed. Anthracitization is the transformation of bituminous coal into anthracite. The moisture content of fresh-mined anthracite generally is less than 15 percent. The heat content of anthracite ranges from 22 to 28 million Btu per short ton (26 to 33 MJ/kg) on a moist, mineral-matter-free basis. The heat content
Coal in Australia tailings and chitter). The Federal Government has, as part of its pledge to mitigate global warming, committed A$100 million to commission a climate change-fighting "clean coal" and carbon sequestration research institute to make Australia a leader in this emerging technology. Carbon sequestration technology is not expected to be commercially viable for at least 5 to 10 years, but the Federal Labor government argues that it is a vital technology given Australia's reliance on coal-fired electricity. The merits of "clean coal" have been highly disputed by some technical experts and environment awareness groups. Coal in Australia Coal is mined in every
