Metallurgical coke sounds like a soda beverage, but it's not. It is a refined carbon product made from a special kind of coal. Using extremely high temperatures, coal can purified into coke -- which is then used in the iron and steel making processes. One of the most important steps in the coke-making process is choosing the right coal to use as a raw material.

In coke stabilization, the coke yield was dropped from a height of 5m into a metal receiver once. The stabilized coke was then screened through vibrating round hole screens of sizes <10, 10-20, 20-40, 40-60, 60-80 and > 80mm. For micum drum test, 50 kg of the screened coke was subjected to 25rev/mm for 4min in a steel drum and screened again.
