Coal drying. Coal preparation plants that employ fine coal cleaning by froth flotation can produce an unacceptable amount of moisture in the product. Thermal drying, in which the wet coal is dried in the hot gas generated by a coal-or gas-fired burner, is used in some plants to reduce the moisture content. Refuse and tailings management.

Lower quality coal such as sub-bituminous or brown coal can be refined to remove moisture and other impurities. This increases the efficiency of the coal as a fuel and reduces emissions of greenhouse gases and other pollutants, when the coal is burned. In Victoria the brown coal is upgraded by the Coldry Process.

How is Iron Refined from Ore with pictures

How Is Iron Refined From Ore With Pictures

To purify and strengthen iron, materials like coke are mixed in with it to remove oxygen. To coax the oxygen atoms away from the ore requires heat and an alternate atomic partner for the oxygen to bond to. Carbon fills this role nicely, and is readily available in the form of everyday charcoal, or coke, a form of carbon made from coal.
