1. Iron ore - supply and demand outline 1.1 Types of iron ore Iron ores can be classified in different ways. The most important has to do with the iron content. In many cases, ore with a total iron content of 60% to 63%, or greater, is regarded as high grade, and ore with a lower iron content is regarded as low grade.
