This is a list of countries by coal production ranking countries with coal production larger than 5 million tonnes as of 2023. Coal production (million tonnes) Country
Metallurgical coal or coking coal [1] is a grade of coal that can be used to produce good-quality coke. Coke is an essential fuel and reactant in the blast furnace process for primary steelmaking. [2] [3] [4] The demand for metallurgical coal is highly coupled to the demand for steel. Primary steelmaking companies often have a division that ...
A coke oven at a smokeless fuel plant, Abercwmboi, South Wales, 1976. The industrial production of coke from coal is called coking. The coal is baked in an airless kiln, a "coke furnace" or "coking oven", at temperatures as high as 2,000 °C (3,600 °F) but usually around 1,000–1,100 °C (1,800–2,000 °F). [2]
As a fossil fuel burned for heat, coal supplies about a quarter of the world's primary energy and two-fifths of its electricity. [4] The largest consumer and importer of coal is China. China mines almost half the world's coal, followed by India with about a tenth. Australia accounts for about a third of world coal exports, followed by Indonesia ...
The People's Republic of China is the largest producer of coal in the world, while Australia is the largest coal exporter. [1] Countries with the largest proven black coal reserves are the United States (250.2 billion tonnes), Russia (160.3 billion tonnes), Australia (147.4 billion tonnes), China (138.8 billion tonnes) and India (101.3 billion ...
[31] [32] [33] After boycotting Australian coal in 2020, coking coal imports from Mongolia [34] and the US grew. [31] Also Russia sought to expand its coal exports to China due to declining demand in Europe because of the energy transition and the political tensions between Russia and Western countries over the Russian invasion of Ukraine. [33]
A coking factory or a coking plant is where coke and manufactured gas are synthesized from coal using a dry distillation process. The volatile components of the pyrolyzed coal, released by heating to a temperature of between 900°C and 1,400 °C, are generally drawn off and recovered. There are also coking plants where the released components ...
Production of coal grew by a compound annual growth rate (CAGR) of 3.19%, and production of lignite declined by a CAGR of 1.60% over the last 10 years. [21] Coal mining is one of India's most dangerous jobs. [24] India targets to increase its coal production to 1,200 million metric tons (1,300 million short tons) by 2023–24. [25]
