According to a report from Antaike, a Chinese state-owned research firm, based on statistics from the US Geological Survey (USGS), the global bauxite resources totaled 55-75 billion tons by the end of 2021, with proven reserves of nearly 32 billion tons.
Calculated based on 5 tons of bauxite for 1 ton of primary aluminum production, the global aluminum industry has consumed 8 billion tons of bauxite since 1886, accounting for only 20% of the total global reserves.
On a base of a mining output of 390 million tons in 2021, the static reserve life is 82 years.
