Coal | National Geographic Society

22/12/2012· In order to produce steel, iron ore must be heated to separate the iron from other minerals in the rock. In the past, coal itself was used to heat and separate the ore. However, coal releases impurities such as sulfur when it is heated, which can make the resulting metal weak.

Coal - Wikipedia

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands—called coal forests—that covered much of the Earth's tropical land areas during the late Carboniferous (Pennsy…

Since the x-ray technology is capable of detecting atomic differences in the rock, the almost pure carbon in the coal is relatively easy to separate from the waste rock. And the ash content in the product can be determined by varying the threshold values. This offers a wide range of applications for the coal. With this method, the de-centralised pre-concentration of coal in small, remote mines allows the coal to be separated from the waste rock…

Coal Refuse — Center for Coalfield Justice

After coal is mined, the raw coal must be processed and cleaned to prepare it for combustion. The first basic step is to put the raw coal through a series of shakers that separate rock material from the coal and results in a solid waste, generally called “coarse coal refuse.” The second step involves using chemicals that remove any other material from the coal and results in a liquid waste ...

Igneous rocks form when molten rock (magma or lava) cools and solidifies. Sedimentary rocks originate when particles settle out of water or air, or by precipitation of minerals from water. They accumulate in layers. Metamorphic rocks result when existing rocks are changed by heat, pressure, or reactive fluids, such as hot, mineral-laden water. Most rocks are made of minerals containing silicon ...
