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 ...

In very simple terms, the process of converting ROM coal into marketable products is called coal preparation. Levels of cleaning Coal preparation results in at least two product streams, the clean coal product and the reject. Generally, five levels of preparation can be identified, each being an incremental level of cleaning over the previous one:

THE EFFECTS OF PROCESS CHEMISTRY ON COAL FLOTATION Coal is an ideal candidate for flotation. Its organic nature suggests a high level of natural hydrophobicity and its low density will assist in the levitation of particles in the flotation cell. Figure 2, below summarises the concept of contact angle.
