(i) The varieties of coal found in India are anthracite, bituminous, lignite and peat. (ii) Characteristic of each type of coal are: Anthracite coal — It is shiny and lustrous, almost jet black. Bituminous coal — It is hard, black and compact and makes up almost 80% of the world’s total coal output.
Similarly, Which coal is best?
Anthracite is the best quality of coal which carries 80 to 95 per cent carbon content. It ignites slowly with a blue flame. It has the highest calorific value.
Additionally, What are the different types of coal Class 10? Hint: There are four different types of coal. They are peat, lignite, bituminous coal and anthracite.
What are the different types of coal What are their uses Class 9?
There are four types of coal – peat, lignite, bituminous and anthracite. Each type has different proportions of carbon and thus, have different uses. Peat – This type of coal has less than 40% to 50% of carbon, while the remaining is moisture. This makes it difficult for us to ignite and cannot be easily used.
Where are coal found in India?
Coal deposits are primarily found in eastern and south-central India. Jharkhand, Odisha, and Chhattisgarh accounted for almost 70% of the total known coal reserves in India.
Who has the best quality coal?
Australian coal is generally amongst the best quality coal in the world, regarded highly for its energy content, low impurity and its efficiency as a coking agent in the production of steel.
Which coal is considered best and why?
Anthracite, also known as hard coal, is a hard, compact variety of coal that has a submetallic luster. It has the highest carbon content, the fewest impurities, and the highest energy density of all types of coal and is the highest ranking of coals.
Which type of coal is the cleanest and most efficient?
Anthracite is a very hard form of coal with an extremely high carbon content. Anthracite also burns the cleanest of any coal, but unfortunately it is the least abundant and hardest to reach form of coal.
What are the different types of coal what are the uses of coal?
Thermal coal is mostly used for power generation, cement manufacturing and other industrial purposes, while metallurgical coal is used primarily for manufacturing iron and steel. Anthracite is the most mature coal and thus has the highest carbon content of any type of coal.
What are the different types of coal What are the uses?
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.
What are the different types of coal What are their uses Class 8?
Anthracite, bituminous, lignite are the major types of coal. Anthracite is the hardest coal with higher carbon concentration and energy. Lignite is the softest coal with low carbon concentration but high oxygen and hydrogen. Whereas bituminous is in moderate state.
What are the different types of coals what are their uses?
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.

Where coal is found?
Coal is mainly found in three regions: the Appalachian coal region, the Interior coal region, and the Western coal region (includes the Powder River Basin). The two largest coal mines in the United States are the North Antelope Rochelle and Black Thunder mines in Wyoming.
Which state produces most coal in India?
Jharkhand is the largest coal-producing state in India. The top coal-producing states are Jharkhand, Orissa, Chhattisgarh, West Bengal, Madhya Pradesh, Telangana and Maharashtra.
Which region in India is richest in coal?
The Damodar valley is rich in coal & it is also known as the prime core of coking coal in India.
Which country produces the best coal?
China is by far the leading hard coal producer worldwide. In 2018, the economic powerhouse was responsible for over 3.5 billion metric tons of hard coal produced. In 2019, China was also the leading global coal consumer, at 82 exajoules.
Is brown coal better than black coal?
Brown coal (lignite) is classed as a low-rank coal because it has a high ash and moisture content, and less carbon, which means that it produces less energy when it is heated. … Black coals are ranked higher because they are harder, have more carbon, less ash and less moisture and thus a higher energy content.
Who owns Australia’s coal mines?
Major Australian coal mining companies)
| Company | Total coal mined (Million tonnes (Mt) pa) |
|---|---|
|
Rio Tinto Coal Australia Pty Ltd | 5.80 |
| Vale | 8.00 |
| Wesfarmers Coal Ltd | 2.16 |
| Whitehaven Coal Mining Pty Ltd | 23.1 |
Why anthracite is considered to be the best variety of coal?
Answer: Anthracite is best variety of coal as it contains largest amount of carbon in it. It has 92%-97% carbon content. It is more combustible than other forms of carbon.
Why are bituminous and anthracite considered to be very good quality coal?
In bituminous and anthracite constituents more carbon in compare of Lignite and peat. coal is converted into coke, coal gas,coal tar, ammoniacal solution ; by using destructive distillation method and coke , coal gas ant tar are used in many important work in factory.
Why coal is the best energy source?
Cheapest source of energy. It is by far cheaper than nuclear, natural gas, oil. … Coal also provides a stable source of energy (no Arab oil embargoes, no sudden scarcity like you experience with natural gas) and there is a very plentiful supply both in the U.S. and in other foreign countries.
What is the cleanest coal?
The ranks of coal (from most to least carbon content) are as follows: anthracite, bituminous coal, sub-bituminous coal, and lignite. The coal with the highest carbon content is the best and cleanest type of coal to use.
What is the cleanest burning coal?
Anthracite is considered the cleanest burning coal available. It produces more heat and less smoke than other coals and is widely used in hand-fired furnaces. Some residential home heating stove systems still use anthracite, which burns longer than wood.
What is the dirtiest type of coal?
The combustion of lignite produces less heat for the amount of carbon dioxide and sulfur released than other ranks of coal. As a result, environmental advocates have characterized lignite as the most harmful coal to human health.
