Anthracite Coal What is Anthracite| Uses| Formation| Reserves
Oct 22, 2021 Anthracite coal is formed after the formation of bituminous coal, when it undergoes further changes in its composition through combined pressure and high temperature, which forces out oxygen and leaves rich carbon deposits. It is a process which takes millions of years. Where is Anthracite Coal Found (Major Reserves)

Sep 08, 2018 Transformation of the bituminous coal into anthracite is called ‘Anthracitization’. It was formed during the Carboniferous Age, when the dense green vegetation that thrived during the tropical climate of the time fossilized.

Anthracite
Anthracite is similar in appearance to the mineraloid jet and is sometimes used as a jet imitation. Anthracite differs from ordinary bituminous coal by its greater hardness (2.75–3 on the Mohs scale), its higher relative density of 1.3–1.4, and luster, which is often semi-metallic with a mildly green reflection. It contains a high percentag
