Metallurgical coal BHP
Metallurgical (met) coal (sometimes referred to as coking coal) is a naturally occurring sedimentary rock found within the Earths crust. Categories of met coal include hard coking coal, semi-hard coking-coal, semi-soft coking coal and pulverized coal for injection (PCI).
What are the different types of coal American
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 carbon content.

Coal Cleaning an overview ScienceDirect Topics
Chemical coal cleaning processes are being developed to remove the organic sulfur, but these are not used on a commercial scale. An added benefit of coal cleaning is that several trace elements, including antimony, arsenic, cobalt, mercury, and selenium, are generally associated with pyritic sulfur in raw coal, and they too are reduced through the cleaning process.

Modular Coal Preparation Plants
Modular Coal Preparation Plants (MCPP) prepares coal for a cleaner burning process, enhanced calorific value and cleaner emissions. MCPP s consist of several modules including a raw coal preparation (crushing and screening station), a coal feed and washing module (jigging and Heavy Medium cyclone) as well as a dewatering module.
122 Coke Production
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 .
FischerTropsch process Simple English Wikipedia the
Coal-based FischerTropsch factories start out with coal, gasify the coal, and then use the resulting gas as feed stock for the Fischer-Tropsch process. These factories can produce large volumes of CO 2 in this way. One of the main reasons for this approach is the large amounts of energy required for a coal-based gasification process.
