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. Steam coal - also known as thermal coal - is mainly used in power generation. Coking coal - also known as metallurgical coal - is mainly used in steel production.

There are six main types of coal that are regularly used by humans:
Peat
Peat is formed from decaying vegetation, and is considered to be the precursor of coal. Peat is an important industrial fuel in some regions, including Ireland and Finland. When dehydrated, peat becomes an effective absorbent for fuel and oil spills on both land and water.
Lignite
Lignite is formed from compressed peat, and is often referred to as brown coal. Lignite is a low ranking and highly volatile coal which is used mainly in power stations. It is sometimes found in European briquettes.
Bituminous/Sub Bituminous Coal
Formed from compressed lignite, bituminous coals are a dense, sedimentary rock which is usually black in colour, but can sometimes be a 8dark brown. These coals are widely used in the manufacturing of briquettes, and are also used in power stations, for heat and power applications in manufacturing, and to make coke.
Steam Coal
Steam coal is the stepping stone between bituminous coal and anthracite. It was once used to fuel steam trains, and as the use of them declined, so did the use of steam coal.
Anthracite
Anthracite is the highest rank of ignitable coal. It is hard, black and glossy, and as a natural smokeless fuel, is used primarily for residential and commercial space heating. Anthracite is the main source of many manufactured fuels, and provides a good heat output, and long burning times.
Graphite
The technically highest ranking coal, graphite is difficult to ignite, and is rarely used as a fuel. It is mostly used in pencils, and as a lubricant in its powdered form.
Steam coal - also known as thermal coal - is mainly used in power generation.
Coking coal - also known as metallurgical coal - is mainly used in steel production.
Activated carbon - used in filters for water and air purification and in kidney dialysis machines.
Carbon fibre - an extremely strong but light weight reinforcement material used in construction, mountain bikes and tennis rackets.
Silicon metal - used to produce silicones and silanes, which are in turn used to make lubricants, water repellents, resins, cosmetics, hair shampoos and toothpast.
