Iron ore is a natural/raw material that is mined around the world. The material is processed to allow its use in the iron/steel making industry. Initially, this involves crushing followed by screening to separate the ore into lumps and fines. If the iron content of the processed ore is >60% then it can be shipped directly to the plants.
The IMSBC Code definition for iron ore refers to cargo in the size range of up to 250mm, and iron ore fines 10% or more of fine particles of less than 1mm and 50% or more of particles less than 10mm. Moisture contents quoted for iron ore fines typically vary between 6 to 12%, with iron ore having lower moisture content.
