    Densities for common bulk cargoes vary from 0.6 tons per cubic meter for light grains to 3 tons per cubic meter for iron ore. The overall cargo weight is the limiting factor in the design of an ore carrier, since the cargo is so dense. Coal carriers, on the other hand, are limited by overall volume, since most bulk carriers can be completely

    prisms of ore were the content of metallic iron and the percentage of probably recoverable ore. Some ore is invariably left for roofs or pillars in mining operations, and much is necessarily impossible of recovery on account of faults. About 80 to 90 per cent has been regarded as the recoverable proportion.
