Clean coals derived from the coal washing process are used for coke production in coke ovens. The coking process is conducted in temperatures above 1000 °C. At such a high temperature, changes in the mineral matter of coal occur (Strugała 1998). These changes facilitate the release of mercury from coal and only a small amount of it …Web
