Reduction swelling behaviour of iron ore pellets
• The dynamic swelling of iron ore pellets in a simulated blast furnace atmosphere is considerably more restrained than the corresponding static swelling. Thus, the reduction swelling behaviour of iron ore pellets should preferably be studied DYNAMICALLY under simulated blast furnace conditions to obtain the most realistic results.

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.
