Safe carriage of Iron ores other iron concentrates in bulk

Sponge Iron or Direct Reduced Iron DRI This is produced from iron ore and is used in the manufacture of steel It involves heating the iron ore at low temperatures without allowing it to come in contact with air It is therefore important to allow the piles of sponge iron to be weathered before shipping so that its temperature drops
