processes coal to remove dirt, rock, ash, sulfur, and other unwanted materials, increasing the heating value of the coal. TRANSPORTING COAL After coal is mined and processed, it is ready to be shipped to market. The cost of shipping coal can cost more than the cost of mining it. Most coal is transported by train, but coal can also be ...

Mineral fuels like coal and petroleum are also non-metallic minerals. Minerals can be extracted by mining, drilling or quarrying. Mining is the process of extracting minerals from rocks buried under the earth's surface. Meanwhile, in open-case mining, minerals that lie at shallow depths are extracted by removing the surface layer.
