The coal in different deposits have different compositions, therefore, coal is classified in various categories. Sub-bituminous coal or black lignite is a category of coal which appears as grey-black or dark brown. It ranges from hard to soft as it represents an intermediate stage between low quality lignite and higher quality bituminous coal.
