Mining and Refining – Process. The Bayer Process was invented and patented in 1887 by Austrian scientist Karl Josef Bayer. Two to three tonnes of bauxite are required to produce one tonne of alumina. 90% of the global alumina supply of around 90 million tonnes is used in aluminium production. Alumina refineries tend to be located close to

Analysts currently estimate that Indonesia’s nickel mine production will decline by 60% in 2020, and will only maintain two-thirds of the 2019 production level by 2029. Other mining sectors, such as bauxite, copper and tin, will eventually face increasingly stringent export restrictions on unprocessed minerals.
