1.6. General Flow Sheet Of a Mineral Beneficiation Plant: Flow sheet is a typical representation of general processes used in a given plant to obtain the end product most conveniently. For the same end product using similar ores the operating conditions may vary from place to place however the general flow diagram remains the same.
Coal is a good example of a material that is typically naturally hydrophobic, because it is mostly composed of hydrocarbons. Chemical treatments to render a surface hydrophobic are essentially methods for selectively coating a particle surface with a monolayer of non-polar oil. 100 0 Assay % Metal Recovery
accomplished during grinding in ball-and-tube mills or roller mills. While thermal energy for drying can be supplied by exhaust gases from separate, direct-fired coal, oil, or gas burners, the most efficient and widely used source of heat for drying is the hot exit gases from the pyroprocessing system.

It pulverizes coal by applying hydraulically-loaded grinding pressure through three grin- ding rollers onto a rotating bed of coal. Grinding pressure can be adjusted to account for variations in coal grindability and desired product fineness. Raw coal is fed through a centrally located feed pipe to the center of the grinding table.
