Iron ore tailing (IOT) is a solid waste generated after the beneficiation process of iron ores. Further, due to the complex nature of ore, the amount of IOT generated varies from place to place. For instance, in Western Australia, the production of 1 ton of iron ore results in the generation of 2 tons of IOT [17].
The amount of waste rock that needs to be removed depends on the geometry and location of the ore body, mining method and the composition and stability of the bedrock. The ratio of waste rock/ore is called stripping ratio. For example, a stripping ratio of 2:1 means that 2 tonnes of waste rock needs to be removed to mine 1 tonne of ore.
