Mining Industry Profile | Department of Energy

Minerals are mined either underground or through surface methods like openpit mining. Approximately 66% of coal and 97% of nonfuel minerals are extracted through surface mining methods. Both mining methods go through a process involving three general stages.

Coal Formation | Miners Museum – Glace Bay Nova Scotia Canada

Coal beds consist of altered plant remains. When forested swamps died, they sank below the water and began the process of coal formation. However, more than a heavy growth of vegetation is needed for the formation of coal. The debris must be buried, compressed and protected from erosion.

What is clean coal technology? | HowStuffWorks

Some clean coal technologies purify the coal before it burns. One type of coal preparation, coal washing, removes unwanted minerals by mixing crushed coal with a liquid and allowing the impurities to separate and settle. Other systems control the coal burn to minimize emissions of sulfur dioxide, nitrogen oxides and particulates.

Coal Wikipedia

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.
