chromium ore quality
Chromium Ore
A characteristic of chromium ore is that it can settle into a compact mass during the voyage making it impossible to discharge from containers by gravity. Chromium ore contains more than 3 to 4% moisture and in settling may behave like a slimy mass as a result of the movements of the ship. Must not be placed in contact with manganese ore.
