In addition, Australia, India, Germany and South Africa account for 29 percent of the world's total coal production. The above-mentioned seven countries or regions account for 80 percent of the world's total coal production. The proven coal reserves are more than 63 times the oil reserves. Abundant countries are also major producers of coal.

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). This process vaporizes or decomposes organic substances in the coal, driving off volatile products, including water, in the form of coal-gas and coal-tar.
productivity. The process is also characterized by flexibility regarding various raw materials, including iron ore fines, steel mill waste and non-coking coal. This paper outlines the features and development status of Kobe Steel's coal-based reduction processes, each employing an RHF for reducing carbon composite agglomerates.
Coking coal is a coal that has been deeply buried and as a result has very specific and rare characteristics. Less than 5% of all of the coal deposits globally are coking quality, and many of these vary significantly in terms of parameters and coking qualities. West Cumbria coals are high volatile, hard coking coal. They have:

The Coal Resource: A Comprehensive Overview of Coal 23 The coking coal is crushed and washed. It is then 'purified' or 'carbonised' in a series of coke ovens, known as batteries. During this process, by-products are removed and coke is produced. Blast Furnace The raw materials – iron ore, coke and fluxes (minerals such as limestone ...
among many in the coal production process, albeit an important one. If other constraints had not been solved later in the nineteenth century, the seven-fold increase in European coal production between 1850 and 1900 would not have been possible. One of those constraints was ambient explosive gas.

direct use of non-coking coal as the fuel/reducing agent and lump ore as the iron oxide feed. While the use of fine coal via pulverized coal injection is available for both technologies, coal briquetting is applicable to the Corex only. By coal briquetting it is possible to mix low-quality, low-cost coal fines with coals of higher grades.
The process gasifies non-coking coal in a smelting reactor, which also produces liquid iron. The gasified coal is then fed into a shaft furnace to remove oxygen from iron ore lumps, pellets or sinter and finally, this direct reduced iron (DRI) is fed to the smelting reactor.
