Alumina is the key raw material used to produce primary aluminium. Mined bauxite ore is refined into alumina through what is known as the Bayer process. The process, discovered in 1887, extracts alumina from bauxite through crushing, dissolving it in caustic soda, filtration and an electrolytic process.
As of today, the royalty for plant-grade bauxite is set at Rs 750 per ton for captive consumption, whereas the royalty for non-plant-grade bauxite is at Rs 300. The mining fraternity fought a decade-long legal battle against the amount of royalties to be paid from 2007 to 2017 and received a verdict in their favour.
