Coal Mining and Processing Methods

Longwall mining additionally requires large coal reserves to justify the capital cost of longwall equipment. As surface mining in the Powder River and Rocky Mountain Basins proceeds, it is likely that the stripping ratios (overburden to coal) will exceed an economic limit. ... Today, the "heavy-media" process using magnetite is standard for ...

magnetite is used almost entirely by the New South Wales coal mining industry during coal beneficiation. When finely milled, magnetite remains suspended in water, producing a dense medium suitable for separating impurities from coal. The magnetite is easily recovered by applying a magnetic field.
