Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed if dead plant matter decays into peat and over millions of years the heat and pressure of deep burial converts the peat into coal.

Advances in dry jigging improves coal quality T here are many advantages to upgrading coal with dry jigging technology. The most obvious is the lack of process water, which eliminates the need for fines dewatering and slurry confinement. Dry jigging eliminates the clean coal moisture penalty associated with wet processing.
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.
