Why is coal not classified as a mineral?
Minerals: Minerals are naturally-formed substances that have a specific chemical makeup. They are created when elements combine. Minerals are non-organic and most have a set crystalline structure.
Coal
Coal is a black or brownish-black sedimentary rock that can be burned for fuel and used to generate electricity.It is composed mostly of carbon and hydrocarbons, which contain energy that can be released through combustion (burning). Coal is the largest source of energy for generating electricity in the world, and the most abundant fossil fuel …

Beginner's Guide to Strip Mining | An Underground Miner
Once miners fracture a coal seam, they load the fractured coal onto conveyor belts and trucks for hauling. The mining operation sends coal collected from a seam to treatment plants near the mine site. This process removes all unwanted material, such as dirt or sulfur, from the coal before its use in power plants and other coal-based …
