Alumina Production an overview ScienceDirect Topics
This process involves the separation of alumina from unwanted components such as iron, titanium, silica, calcium, vanadium, manganese, etc., in bauxite. In this process, bauxite is heated along with the caustic soda at high pressure (~30 atm), resulting in the formation of sodium aluminate (reactions (1)–(4)) (Gil, 2005; Ma et al., 2009).
