Coke (fuel) Raw coke. Coke is a grey, hard, and porous coalbased fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a ...

Grinding. By using Bond's work index for the process calculation, this phase entails keeping the material within the mill for a set amount of time (with or without grinding balls). This index considers factors such as feed size, mill speed, material recirculation, target fineness, and ore hardness. Iron ore is separated into fine particles ...

During the handling of DRI products, breakage and spillage can account for significant losses of product. Handling losses can exceed the impact of total iron content or gangue content on the total yield from iron ore to liquid steel. However, handling losses often are absorbed by different operating areas and are not accounted for in total.
