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.
Iron ore from five hills contains more than 67.0% Fe. This is regarded as high-grade iron ore and compares well with other iron ores from the main iron ore producing nations. The silica and alumina contents of these ores are also below 1.2% and 1.0%, respectively, with correspondingly low levels of S (<0.006%) and P (<0.05%).
The understanding of lower-grade iron ore mineralogy and the subsequent characterization of lower-grade iron ore will allow for the efficient processing of the ores and the optimization of downstream smelting processes. SEM-based technologies are expected to play a crucial role in the nondestructive data collection needed for such future ventures.
