All coals, regardless of whether they are caking or coking coals, leave a solid carbonaceous residue at the end of the carbonization process. Chars, if heattreated to extreme temperatures, ≥2500 °C, do not form graphite, while cokes do. That is, chars are nongraphitizable, while cokes are graphitizable [A]. Type.

Currently, the wet coal beneficiation process is the predominant method for coal upgrading. The wet beneficiation processes include heavy media separation, cyclone (water only), froth flotation, and spiral separation [23,24]. The use of these technologies depends on the particle size of the feed and the quality of the product required.

The blended coal mass is heated for 12 to 20 hours for metallurgical coke. Thermal energy from the walls of the coke chamber heats the coal mass by conduction from the sides to the middle of the coke chamber. During the coking process, the charge is in direct contact with the heated wall surfaces and develops into an aggregate "plastic zone".
