Bauxite consumption per ton of alumina has increased in recent years (from around 2.7 tons in 2005) due to declining quality of bauxite resources and now three tons of bauxite are required to produce one ton of alumina and two tons of alumina are required for the production of one ton of primary aluminum metal.
Bauxite is finely ground in mills, then mixed with a recycled caustic soda solution and steam in digester vessels operating at high temperature and pressure. This dissolves the alumina content of the bauxite. The solution is then cooled in a series of flash tanks.

The process stages are: 1. Milling The bauxite is washed and crushed, reducing the particle size and increasing the available surface area for the digestion stage. Lime and "spent liquor" (caustic soda returned from the precipitation stage) are added at the mills to make a pumpable slurry. 2. Desilication
The embodied energy values were 153 MJ/t ore, 55 MJ/t ore and 8329 MJ/t concentrate for iron ore, bauxite and copper concentrate respectively. These results show that loading and hauling made the largest contributions (approximately 50%) to the total greenhouse gas emissions for the mining and processing of iron ore and bauxite.
