Question: Where is metallurgical coal found?

How is metallurgical coal produced?

Metallurgical-grade coal is heated to over 1000 degrees Celsius in the absence of oxygen, and then quickly cooled in water or air to produce a hard, porous brick of carbon known as coke.

Which is the most widely used metallurgical coal?

Coking coal is an essential input for production of iron and steel. The largest single use of coal in the steel industry is as a fuel for the blast furnace and for the production of metallurgical coke for reduction of iron ore or for injection with the hot blast.

Is coke obtained from coal?

Coke is produced by heating coal at high temperatures, for long periods of time. This heating is called “thermal distillation” or “pyrolysis.” In order to produce coke that will be used in blast furnaces, coal is usually thermally distilled for 15 to 18 hours, but the process can take up to 36 hours.

Is steel still made with coal?

A third of global steel today is made without coking coal, either through scrap recycling or gas-based steel production; and counting.

Is there an alternative to metallurgical coal?

Blast furnaces need coal, but there is an alternative technology called an Electric Arc Furnace (EAF). This is responsible for approximately 30% of the world’s steel production and does not require coal.

Is coke a cheaper and lower quality form of coal?

In 2019, the average delivered price of coking coal to coke producers was about $146 per short ton—almost four times higher than the average price of coal delivered to the electric power sector.
