simple operational rules are able to be incorporated into DES models of the mining supply chain relatively easily, allowing the DES model to provide a realistic representation of the export supply chain as a whole. However in some mining supply chains, the process of moving ore from pit to port is significantly more complicated.

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.
