processing. The ore is crushed and milled to reduce the particle size and make the minerals more amenable to extraction. It is then combined with the process liquor and sent in a slurry form to a heated pressure digester. Conditions within the digester (concentration, temperature and pressure) are set according to the properties of the bauxite ore.
