    Once a suitably sized deposit of a mineral has been found, mining can begin. In ancient times mining and mineral processing were very primitive and the main method used to extract ores was digging by hand. Mining is largely divided into surface and underground mining. Minerals are often found in river beds, beach sands and other sandy areas.

    Many breakers and washeries efficiently handle the coarser sizes, but waste the coal fines. This problem is assuming major importance due to the increase in the amount of coal fines being produced by the mechanization of coal mining. Flotation offers a very satisfactory low-cost method for recovering a fine, low ash, clean coal product at a profit.

    Mining & Processing. Before the coal can be removed from the ground, the topsoil and dirt above it is removed using scrapers. This soil is usually removed ahead of the pit and carried behind to place on top of reclaimed areas or backfill. The dirt that lays on top of the coal (overburden) follows the same pattern.

    mining: room-and-pillar and longwall mining. In room-and-pillar mining, coal deposits are mined by cutting a network of ''rooms'' into the coal seam and leaving behind ''pillars'' of coal to support the roof of the mine. These pillars can be up to 40% of the total coal in the seam – although this coal can sometimes be recovered at a later stage.
