Coal
Coal is a solid, combustible mineral, black or dark brown in color, composed primarily of carbon, along with small amounts of hydrogen, oxygen, nitrogen, sulfur, and other elements.
Coal is the most important solid fuel used in the generation of electric power. Its quality depends on the content of volatile matter, fixed carbon, inherent moisture, and oxygen.
Typically, coal quality improves with higher fixed carbon content and lower moisture and volatile matter. Bituminous coals are the most commonly used type.
MCI primarily markets coal from Norte de Santander, Colombia, known for its high calorific value (high BTUs) and low sulfur content.
