What are the 4 types of coal?
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.
Is lignite the worst coal?
Lignite is the most health-harming form of coal, given the higher amount of pollution resulting from its combustion. European countries are the biggest producers and consumers of lignite coal worldwide.
What is lignite also called?
Lignite, often referred to as brown coal, is a soft brown combustible sedimentary rock that is formed from naturally compressed peat. It is considered the lowest rank of coal due to its relatively low heat content.
How does lignite turn into coal?
Burial and accumulation can occur for several thousands of years, producing several meters of partially decayed plant matter known as peat. When this peat is deeply buried, water and other compounds is squeezed out from the increasing pressure and the lowest quality of coal, lignite, begins for form.
Is lignite A coal?
Lignite: Lignite coal, aka brown coal, is the lowest grade coal with the least concentration of carbon. Lignite has a low heating value and a high moisture content and is mainly used in electricity generation.

What is lignite mining?
Lignite, often referred to as brown coal, is a soft, brown, combustible, sedimentary rock formed from naturally compressed peat. Lignite is mined all around the world and is used almost exclusively as a fuel for steam-electric power generation.
How do you use lignite?

Where is lignite coal found in India?
Indian lignite deposits occur in the Tertiary sediments in the southern and western parts of peninsular shield particularly in Tamil Nadu, Puducherry, Kerala, Gujarat, Rajasthan and Jammu & Kashmir. The total known geological reserves of lignite as on 1.4. 2012 were about 41.96 billion tonnes.
