Magnetite

Using magnets, magnetite can be easily recovered from the waste and coal streams and then reused in the coal separation circuit. Recyling the magnetite provides a cost saving to the operator, and is an environmentally conscious method of utilizing this valuable resource. About 90% of the magnetite can be recovered for reuse from the process, but the remaining 10% must be must be replaced.

Losses in the coal supply chain

Coal processing by separation at preparation plants refines coal further and is where most of the mass loss occurs. Value is added by reducing ash content and improving heating value, thus providing a much more saleable product for the market. As soon as the coal leaves the mine, mass loss can occur either through natural deterioration of the fuel, through spillage or dust, or in extreme cases ...

Coke Production

The coking time is determined by the coal mixture, moisture content, rate of underfiring, and the desired properties of the coke. When demand for coke is low, coking times can be extended to 24 hours for blast furnace coke and to 48 hours for foundry coke. Coking temperatures generally range from 900° to 1100°C (1650° to
