• Safe carriage of Iron ores other iron concentrates in bulk

    In the carriage of iron ore the following precautions should be taken Iron ores are heavy cargoes which occupy a small area for a large weight ie they have a low stowage factor between 0.24­0.80 m3/tonne It is therefore important that the tanktop has sufficient strength to carry certain iron ores.
