2021-1-14 Second on the list of bauxite producers is China, which had an annual production of about 68 million metric tonnes in 2019. That total was more than half of the 124 Mt produced in Asia as a whole. China’s notable production of the ore is partly due to Chalco, one of the world’s biggest producers of primary aluminium.
