Bauxite is processed in alumina refineries by the Bayer process in which Al-containing minerals are dissolved in hot NaOH. The insoluble solids (bauxite processing residue mud and sand) are washed ...

In this situation, alumina refineries in China began to use imported gibbsitic bauxite. The cumulative import of bauxite in China in 2012 reached 39.6 million tons, whereas it was 107.4 million tons in 2021, and the import volume increased by 2.71 times in Fig. 2 (a). The import volume was expected to remain above 100 million tons in 2022.
