Bauxite Mining Market - Global Industry Analysis 2026

The following steps are involved in the extraction of bauxite: selection of bauxite area, mining, crushing, ore transportation, and recovery of land. Generally, one metric ton of aluminum can be extracted from one square meter of land. After mining, the bauxite ore is heated and processed in a pressure vessel along with sodium hydroxide at a temperature of 140°C to 300°C.
