Ore concentrates - Cargo Handbook - the world's largest ...

It is interesting to note that if an iron ore concentrate contains 12% of moisture by weight, this may represent as much as 60% of the contents by volume, since the rock content is so much heavier than the water. Any ore concentrate of high moisture content, will liquefy when energy is applied to it in the form of vibration. This can occur not only by the action of the sea but the
