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.

The primary consideration for the suitability of conveyor systems is the ore body geometry. New conveyor technology is allowing conveyance of material over steep grades. However, in general, conveyors are most suitable for horizontal or shallow dipping ore bodies. Typically uncrushed ore cannot be conveyed at a slope of more than 20 degrees [3].
