Reflectivity of Bituminous Coal
Bituminous coal is a sedimentary rock that is largely composed of carbon and hydrocarbons. It is a form of black coal and is classified as an intermediate rank coal due to its general properties. Bituminous coal is the most abundant form of coal found in the world, and is mined in almost every country around the globe. It is used primarily for energy production, to make coke and as a fuel source. Bituminous coal is extremely valuable due to its ability to produce a range of products.
Due to its predominance in the energy market, the reflectivity of bituminous coal has been studied extensively. Its reflectivity is influenced by several factors, including its grain size, ash content, and the type of coal. Generally, the reflectivity of bituminous coal is lower than that of other types of coal due to the presence of impurities. The components of the reflectivity are closely tied to the chemical and physical properties of the coal.
Research has found that bituminous coal has a broad range of reflectivity values. This range is higher than that of anthracite coal, and it varies based on the coal seam, which can be generally classified as high, medium, or low volume. The reflectivity of higher quality coal is generally higher when compared to lower quality coal. The sheen of bituminous coal can range from semi-gloss to dull, depending on its properties and what type of processing it has undergone.
The reflectivity of bituminous coal can be affected by various chemical and physical processes during its formation or at the time of mining. These processes can reduce the reflectivity, increase the reflectivity, or cause a change in the sheen of the coal. Reflectivity can also be altered by how it is stored, processed, and handled. For example, the degree of oxidation can alter the reflectivity, making it either more reflective or less reflective.
Bituminous coal is valued for both its energy and its reflectivity. It has been found that the nature of the reflectivity depends on the quality of the coal, meaning that higher quality coal will typically have a higher reflectivity than lower quality coal. This is highly dependent on the way the coal is processed, mined, stored, and handled. Thus, the reflectivity of bituminous coal can vary quite considerably, depending on its characteristics and the treatment it underwent.
Overall, bituminous coal is widely used and extremely valuable due to its energy and reflectivity properties. Research has found that its reflectivity can vary greatly depending on the quality, property, and treatment of the coal. Therefore, understanding the reflectivity of bituminous coal is an important factor in understanding the value and potential of this mineral resource.
