Abstract
Coke is mixed with bituminous coal and the mixture is converted into briquettes. To obtain high-quality and high-strength briquettes, the temperature of the coke is adjusted, prior to mixing, to such a level that when the mixing takes place, the coke/coal mixture will have a precisely predetermined temperature within the scope of 400.degree.-500.degree. C. The exact temperature within this range is selected in dependence upon the characteristics of the coke and the coal.
