  • Coal breaker

    Coal breakers also remove impurities from the coal (typically slate) and deposit them into a culm dump. The coal breaker is a forerunner of the modern coal preparation plant. Generally speaking, a coal tipple was typically used at a bituminous coal mine, where removing impurities was important but sorting by size was only a secondary, minor concern.

  • Coal is mined by two methods

    Sep 12, 2010To remove impurities, the raw run-of-mine coal is crushed and then separated into various size fractions. Larger material is usually treated using 'dense medium separation'. In this process, the coal is separated from other impurities by being floated in a tank containing a liquid of specific gravity, usually a suspension of finely ground magnetite.

  • Coal Preparation

    Coal preparation is the removal of undesirable material from the run-of-mine (ROM) coal by employing separation processes which are able to differentiate between the physical and surface properties of coal and the impurities. Through proper coal preparation, a uniform product is achieved.

  • Heavy metals and coal

    Coal Ash. Burning coal produces airborne compounds, known as fly ash and bottom ash (collectively referred to as coal ash), which can contain large quantities of heavy metals that settle or wash out of the atmosphere into oceans, streams, and land. The amount of fly ash is going up: in 2006, coal plants in the United States produced almost 72 million tons, up 50 percent since 1993.
