Lignite is a inferior grade coal due to less cv and carbon content as compare to that of bituminous coal.
The finest quality coal is called the bituminous coal, it is finer than the lignite coal.
Well, peat is the kind that comes out of dark unicorns.
Through increased overburden pressure.
Yes. Lignite is also known as brown coal. It is not exactly the same as coal (bituminous or anthracite) but it is near the beginning of the process that makes coal. Lignite has about 1/3 to 1/2 the carbon content of coal.
Lignite is the youngest and softest coal; bituminous is mid-grade coal, and anthracite is the hardest and hottest burning coal. Even brown coal.
The finest quality coal is called the bituminous coal, it is finer than the lignite coal.

Bituminous coal or black coal is a relatively soft coal containing a tarlike substance called bitumen. It is of higher quality than lignite coal but of poorer quality than anthracite. Formation is usually the result of high pressure being exerted on lignite.
In India, Bituminous/sub-bituminous coal is used on large scale. Still there are some plants which consumes lignite for combustion.
