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, bright yellow, or deep purple to rusty red. Iron is responsible for the red colour in many of our rocks and the deep red sands of the Australian deserts.

Legitimate interrelation has been found between model tests and actual in mine behavior. It is, however, important to acknowledge the limitations present in model testing. The main difference between model tests and actual in mine results can be contributed to the consolidation that takes place in a mine when ore is blasted against broken muck.

In general, the rarer the ore, the higher its volume per unit (e.g. one unit of Veldspar has a volume of 0.1 m 3, whereas one unit of Arkonor has a volume of 16 m 3). Since mining lasers mine a given volume of ore per minute, it takes longer to mine the rarer ore types. Additionally, each ore reprocesses into a different set of minerals.
