World Coal Association. Coking coal must also have low sulphur and phosphorous contents. Almost all metallurgical coal is used in coke ovens. The coking process consists of heating coking coal to around 1000-1100ºC in the absence of oxygen to drive off the volatile compounds (pyrolysis). This process results in a hard porous material - coke.

Chromium is a steely-gray, lustrous, hard and brittle metal which takes a high polish, resists tarnishing, and has a high melting point. Chromium metal is commercially produced from chromite by aluminothermic reaction, or by roasting and leaching processes. Chromium metal has proven of high value due to its high corrosion resistance and hardness.
Coke Oven Battery A set of ovens that process coal into coke. Coke ovens are constructed in batteries of 10-100 ovens that maybe 20 feet tall, 40 feet long, and less than two feet wide. Coke batteries, because of the exhaust fumes emitted when coke is pushed from the ovens, often are the dirtiest area of a steel mill complex. Coke Oven Gas
