Iron ores are rocks and minerals from which metallic iron can be extracted. There are four main types of iron ore deposit: massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone. These ores vary in colour from dark grey, through to deep purple, rusty red and bright yellow.

Much of the remaining iron ore resources in Brazil consist of lowgrade itabirite ores. Accordingly, a typical beneficiation circuit includes a fourstaged crushing/screening plant, followed by grinding in a closedcircuit ball mill, desliming in hydrocyclones and final ore mineral concentration via multistage reverse flotation and thickening of the final product.
