Manganese is the most consumed metal in the world after iron and aluminium, but most of its uses are hidden from view so its importance for our society is not necessarily very obvious. Over 90% of the manganese used annually goes into metallurgical applications, primarily steelmaking - in fact, you can’t make steel without manganese. But manganese is set to become even more important as we move away from fossil fuels. New battery technologies in development that rely on manganese may revolutionize electric vehicle production; in addition, pretty much all low-carbon energy infrastructure requires vast amounts of steel and, therefore, manganese. Dr Taija Torvela explores where and how manganese deposits form.
