approximately 66% of coal and 97% of non-fuel minerals are extracted through surface mining methods. both mining methods go through a process involving three general stages. the first stage is extraction, which includes blasting and drilling to loosen and remove material from the mine.minerals and mineral products are the backbone of most industries. coal is an organic sediment consisting of a complex mixture of substances. It has a lot of commercial and industrial applications.most mined materials, from hard-rock ores to solid-fuel minerals such as coal, oil shale and industrial minerals, are subjected to some sort of size reduction andor other beneficiation process. often, several mineral processing operations are performed in sequence to produce a marketable product.
though the rise of coal mining was critical, the process began when landowners began to think in new ways about forests. two centuries of irresponsible coal mining has left pennsylvania with more than 2,400 miles of streams polluted by acid mine drainage.removal of the mineral matter which is largely noncombustible and may constitute up to percent of the raw coal, increases the heating value of the coal on a mass basis. although some combustible material is lost as part of the cleaning process, the removal of unwanted material reduces the mass and volume of coal for a processing the coal. after coal comes out of the ground, it typically goes on a conveyor belt to a preparation plant that is located at the mining site. the plant cleans and processes coal to remove dirt, rock, ash, sulfur, and other unwanted materials, increasing the heating value of the coal.
coal found in sedimentary rock, is crushed into the appropriate size and used as fuel for electricity generation or the iron-making process. lumps of coal can be used directly as a fuel. however some coal is first washed to make it into high grade coal. It can also be sorted into various sizes, depending on what the fuel is required for.
