    This process is known as lateritization. Hence, bauxite is an aluminumrich laterite. The accumulation of aluminumrich residuum, as opposed to one enriched in iron, is a function of higher rainfall, but also lower average temperature (around 22 °C rather than 28 °C) 6. However, there are actually two types of bauxites.
