COAL EXTRACTION AND PROCESSING
Coal is also used in the creation of materials such as steel. Steel industries use a specific type of coal called coke. Coke is coal that has been placed in a coking oven to remove all parts of the coal that is not carbon. When coke burns it creates the high temperature .
Beneficiation
History. Iron beneficiation has been evident since as early as 800 BC in China with the use of bloomery. A bloomery is the original form of smelting and allowed people to make fires hot enough to melt oxides into a liquid that separates from the iron.
