    Coal preparation plant - Wikipedia

    A coal preparation plant (CPP; also known as a coal handling and preparation plant (CHPP), coal handling plant, prep plant, tipple or wash plant) is a facility that washes coal of soil and rock, crushes it into graded sized chunks (sorting), stockpiles grades preparing it for transport to market, and more often than not, also loads coal into rail cars, barges, or ships.

    An analysis of medium losses in coal washing plants

    Dense-medium (magnetite in the case of coal), a slurry/suspension having a relative density intermediate to that of valuable mineral and gangue, is generally used as the medium of separation in most coal preparation plants. The medium, being costly, plays a crucial role in determining the economics of any preparation operation.

    Assessing the feasibility of silica-based media for coal

    However, a typical DMC circuit must be modified to recover and reuse the silica-based dense medium in the coal preparation plant. The most significant of these changes involves eliminating the magnetic separator used to recover magnetite from a dilute slurry. This modification may considerably reduce the operating costs in coal preparation plants.
