Aside from cement production, rotary kilns also play a critical role in other industries such as steelmaking and mineral processing. In iron ore pelletizing plants, rotary kilns are used to convert concentrated iron ore into pellets at high temperatures, increasing its value and making it easier to transport.

At the Itakpe iron ore mine, the ratio of waste to ore is 4:1. The ratio of tailings to concentrate is commonly very high, generally around 200:1 [6]. For instance, it has been reported that in Western Australia, on average, the production of 1 tonne of iron ore results in the generation of 2 tonnes of iron ore tailings [7].
