the process of converting coal into coke using the by-product coke oven, the volatile matter in the coal is vaporized and driven off. This volatile matter leaves the coke oven chambers as hot, raw coke oven gas. After leaving the coke oven chambers, the raw coke oven gas is cooled which results in a liquid condensate stream and a gas stream.

example, coal with a relative density* of 1.4 will float in a medium with a relative density of 2.0, while shale with a relative density of 2.5 will sink. Coal is by far the most important material treated in dense medium processes. Exceptions do occur and will be mentioned later but most of the subsequent discussions will be concerned with coal.
