What is Coking Coal. Coke is produced by heating coking coals in a coke oven in a reducing atmosphere. As the temperature of the coal increases, it becomes plastic, fusing together before resolidifying into coke particles. This is known as the caking process. The quality of the resultant coke is determined by the qualities of the coking coals used,...
