  • Anthracite - It is considered to be the highest quality coal as it contains 94 to 98 per cent carbon content.
  • Bituminous - It contains 78 to 86 per cent carbon content. It is a solid sedimentary rock, which is black or dark brown in colour.
  • Lignite - It contains 28 to 30 per cent carbon content. It is used to generate electrical energy.
  • This coal is brown in colour.
  • Peat - This is the first step in the formation of coal. It has less than 27 per cent of carbon content.
  • Peat deposits are gradually changed to lignite coal.
