Because of it's inorganic component, by scientists (metallurgists and geologists) Coal is not considered a true mineral. As we stated earlier, diamonds are considered minerals. This is because, unlike coal, diamonds have crystalline structure. This means that they can be a

07.10.2008 · Coal is not a mineral, it is better to call it a rock. There are several definitions of a mineral, but essentially for a substance to be called a mineral it has to satisfy the following criteria: 1. naturally occurring - yes 2. crystalline - arguable 3. inorganic - definitely not 4. predictable and homogenous - no Coal fails on points 3 + 4, so its not a mineral, even though it is sometimes ...

In general, anything obtained from mining can be called as a mineral. So, for mining purposes, coal may be considered as a mineral. But, for geologists, a mineral is a naturally occurring homogeneous crystalline chemical substance with a definite ...

Well coal is a rock and rocks are made up of one or more minerals. So technically coal is a mineral because it is a rock and rocks are made of minerals.

Coal on the other hand also comes from plants (organic) and is generally considered a mineral. There are also marine animals that make their shells from calcite (calcium carbonate). Calcite is a mineral but since it is secreted by animals to form shells it is inorganic.

Coal also contains minerals, which mostly occur as inorganic crystalline and noncrystalline particles or masses. A coal seam may consist of as much as 50 percent minerals. At more than 50 percent mineral matter, the rock would be termed a carbonaceous shale rather than coal. Most mined coals are less than 20 percent mineral matter, and many coal contracts require less than 10 percent ash yield ...

Explain why coal and a glass marble are not minerals. A mineral has to be naturally occurring, inorganic, solid, have a crystal structure, and have a definite chemical composition. Coal is not a mineral because it is carbon-based and came from fossilized plants. Glass is a non-crystalline solid.

Coal, one of the most important primary fossil fuels, a solid carbon-rich material, usually brown or black, that most often occurs in stratified sedimentary deposits, which may later be subjected to high temperatures and pressures during mountain building, resulting in .

Coal contains variable amounts of largely incombustible mineral matter co-existing with the organic matrix (Bryers, 1996; Crouch, 1994; Gluskoter et al., 1981; Stach ...

Coal mining's advent in South Africa can best be traced to the start of gold mining in the late 19 th century, particularly on the Witwatersrand, with the first coal in appreciable tonnages being extracted on the Highveld coal field close to the nascent Witwatersrand gold mines. However, demand began to grow, slowly at first but then exponentially as the country entered a period of ...

Coal can only be found in the Grasslands biome within Sandstone. According to game files, Coal has a 70% chance to spawn in bands 13-16 blocks below the surface. Coal bands spawn in a very limited depth range compared to metal ores. Bands (seams) of Coal may extend horizontally to reach other biomes and vertically to reach lower or greater depths. In-game Description " A combustible mineral ...

Coal is not a mineral because it does not qualify to be one. A mineral is made of rocks. It is non-living and made up of atoms of elements. Coals on the other hand are carbon-based and came from fossilized plants. By just looking into the origin of coals, these are not qualified to be minerals because they come from organic material and it has no definite

Minerals are the naturally occurring inorganic substances that occur mostly in the form of crystals. Minerals are the compounds that are formed by various elements found in nature. Coal is a naturally occurring organic compound formed by the remains of organisms. Since it is an organic compound it can not be categorized as a mineral. Hence coal is not a mineral.
