As a domain expert in the field of geology and mineralogy, I have a profound understanding of the classification of natural substances. Let's delve into the nature of coal and its categorization.
Coal is a fascinating substance that has played a pivotal role in the industrial development of many nations. Historically, it was indeed considered a mineral due to its origin from the geological processes involving plant material. However, with the advancement of scientific knowledge, our understanding of coal has evolved significantly.
The term "ore" typically refers to a naturally occurring solid material from which a metal or valuable mineral can be extracted at a profit. This definition inherently implies that the substance in question is a mineral, which is a naturally occurring inorganic solid with a specific crystalline structure. Metals, being elements, are also classified as minerals.
Now, coal is primarily composed of carbon, along with various other elements including hydrogen, sulfur, oxygen, and nitrogen. It is formed from the remains of ancient plant life subjected to geological processes over millions of years. This organic composition distinguishes coal from the traditional definition of a mineral, which is inorganic.
The process of coal formation, known as coalification, involves the transformation of plant material into peat, which then undergoes further changes under heat and pressure to become lignite, bituminous coal, and eventually anthracite. This transformation sequence is a result of diagenesis and metamorphism, geological processes that can also affect rocks.
Given this information, while coal was once classified as a mineral due to its economic importance and its extraction from the earth, it is now more accurately described as a sedimentary rock. This reclassification reflects a deeper understanding of its organic composition and the processes involved in its formation.
The distinction between coal and ores is important for various reasons. For one, it affects how we approach the study of coal, its environmental impact, and its role in energy production. As a rock, coal's properties, such as its energy content and the byproducts of its combustion, are critical considerations in the context of sustainable development and environmental conservation.
In summary, coal is not considered an ore in the modern scientific context due to its organic composition and the processes that lead to its formation. It is more appropriately classified as a sedimentary rock, which has significant implications for how we understand and utilize this resource.

It is because originally it was considered a mineral. A naturally occurring solid material from which a metal or valuable mineral can be profitably extracted. Definitions have changed since we learned coal is made of organic components - so it now considered more of a rock.Nov 9, 2014
