Coal Preparation an overview ScienceDirect Topics

Santanu Chakraborty, in Treatise on Process Metallurgy: Industrial Processes, 2014. 6.1.1 Preparation of Coal. Coal preparation aims at the production of coke of suitable quality for smooth and stable blast furnace operation. Coke properties are determined by various factors beside homogeneity of the coal mix. The major factors are crushing fineness, oiling, preheating, and pre-briquetting.

What Is Coal Preparation? Energy.gov

2013-2-21  What Is Coal Preparation? • Coal preparation is the removal of undesirable material from the Run-of-Mine (ROM) coal by employing separation processes which are able to differentiate between the physical and surface properties of the coal and the impurities. Through coal preparation, a uniform product is achieved.

Coal prices and outlook U.S. Energy Information

Coking coal must be low in sulfur and requires more thorough cleaning than coal used in power plants, which makes the coal more expensive. In 2019, the average delivered price of coking coal to coke producers was about $146 per short ton—almost four times higher than the average price of coal delivered to the electric power sector.
