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.
It is part of everyday life: it is used in the generation and transmission of energy, in wiring and in practically all electronic equipment, such as television sets and cell phones. Highlights: • Copper is the third most used metal in the world, after iron and aluminum. • There are records of objects made with this metal dating back to 8,000 years before Christ .
