Coal is classified into four main types, or ranks: anthracite, bituminous, subbituminous, and lignite. The ranking depends on the types and amounts of carbon the coal contains and on the amount of heat energy the coal can produce.
What is Coal explain its different types and uses?
Answer. Coal types: Hard coals. Bituminous coal is harder and blacker than lignite and sub-bituminous coal, and can be divided into two types: thermal and metallurgical. The most significant uses of coal are in electricity generation, steel production, cement manufacturing and as a liquid fuel.

- Anthracite: It is the highest grade of coal containing a high percentage of fixed carbon. …
- Bituminous: It is a medium grade of coal having high heating capacity. …
- Subbituminous: It is black in colour, dull (not shiny) and has a higher heating value than lignite.
What is coal rank?
Coal rank is the measure of the degree of organic metamorphism (coalification) of a coal, ranging from low-rank peat to high-rank meta-anthracite.

Andhra Pradesh, Madhya Pradesh, and Maharashtra are the other significant coal-producing states in India.
What classification is coal?
Based on maceral content and its appearance in a hand specimen, coal is classified into four principal types: clarain, durain, fusain, and vitrain. Coal may also be classified in grades using subjective terms (e.g., “low-sulfur coal,” “high-ash coal”) with reference to their impurities for commercial purposes.
What are the different types of coal Class 10?
Coals are classified into three main ranks, or types: lignite, bituminous coal, and anthracite. These classifications are based on the amount of carbon, oxygen, and hydrogen present in the coal. Coals other constituents include hydrogen, oxygen, nitrogen, ash, and sulfur.

What are the features of coal?
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen.
Where is the coal found?
The largest coal reserves are in the United States, Russia, China, Australia, and India. In the United States, coal is mined in 25 states and three major regions. In the Western Coal Region, Wyoming is the top producer—about 40% of the coal mined in the country is extracted in the state.
What type of rock is coal?
Coal is a combustible sedimentary rock formed from ancient vegetation which has been consolidated between other rock strata and transformed by the combined effects of microbial action, pressure and heat over a considerable time period. This process is commonly called ‘coalification’.
