In coal preparation plant, the control strategy of the separation process is made mainly based on the timely feedback of the clean coal ash. But the results of commonly used gamma-ray coal ash monitor only could reflect the trends of coal quality and fail to satisfy the dynamic amendment of operation parameter.

The traditional wet drum separators in use at most heavy-media coal prep plants use a low intensity magnetic field and they work well. Magnetite is expensive, however, and an any improvement in recovery will likely pay for itself quickly over time. "The existing systems perform well as long as they are operated properly," said Jose Marin ...
