COREX® — SMELTING REDUCTION PROCESS
The coal is charged inside the melter gasifier, so even non-coking coal can be used, which makes a coking plant unnecessary. The high dome temperature exceeds 1,000°C, resulting in cracking of the coal's relieved hydrocarbons and avoiding the formation of tar. ... Toranagallu, India.

Coal
Coal - Anthracite, Bituminous, Lignite: Coals contain both organic and inorganic phases. The latter consist either of minerals such as quartz and clays that may have been brought in by flowing water (or wind activity) or of minerals such as pyrite and marcasite that formed in place (authigenic). Some formed in living plant tissues, and others formed later during …

What are the different types of coal? | American Geosciences …
The coal formation process involves the burial of peat, which is made of partly decayed plant materials, deep underground. The heat and pressure of burial alters the texture and increases the carbon content of the peat, which transforms it into coal, a type of sedimentary rock. This process takes millions of years. Types, or "ranks," of coal are determined by …
