The abrasiveness of a coal can be determined in a number of ways, and the traditional method for coal is based on the procedure given by Yancey, Geer, and Price [28] and described more fully in British St andard [29] as the Index of Abrasion (AI).
Coal reserves Measured tonnages of coal that have been calculated to occur in a coal seam within a particular property. Coal washing – The process of separating undesirable materials from coal based on differences in densities. Pyritic sulfur, or sulfur combined with iron, is heavier and sinks in water; coal is lighter and floats.
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 lowcost method for recovering a fine, low ash, clean coal product at a profit.

Coal loading methods. The grab loading process uses cranes to remove coal from rail cars and transfer it directly into a ship. Alternatively, coal can be loaded from stockpiles immediately adjacent to the berths. This loading method is mostly used at longestablished ports which were designed as multipurpose facilities for loading general cargo by cranes.
