Guinea bets bauxite dominance can reshape aluminium supply: Andy Home
About this update from Rusal
By Andy HomeThe West African country of Guinea has grown to be the world's largest supplier of bauxite, the raw material ultimately transformed into aluminium.It's now looking to use this newfound dominance to exert greater control over both price and industry structure, just as Indonesia has done in nickel and the Democratic Republic of Congo is attempting to do in cobalt.All three resource giants are struggling to rein in mining sectors that have grown too big too fast, swamping global markets and crashing prices.Indonesia is using mining quotas, the Congo export quotas, and Guinea looks minded to implement a mix of both as a way of stopping operators exporting more than their mining quotas allow them to produce.For Conakry, it's also a chance to emulate Indonesia by capturing more of its resource value by moving from bauxite mining to alumina refining.Chinese state aluminium producer Chalco's SSE:601600 commitment to a new $1 billion refinery in the country is a sign the strategy is working.BAUXITE BOOMBauxite is the third most abundant element in the Earth's crust but is mostly too dispersed or too low quality to allow for conversion into alumina.Guinea not only boasts the world's largest reserves of metallurgical bauxite but also produces a high-purity product prized for its natural low silica content.Thanks to heavy Chinese investment, the country overtook Australia as the world's largest bauxite producer in 2023 and now accounts for around 40% of global output and 70% of the seaborne export market.Guinea's exports jumped by 25% year on year to 183 million metric tons in 2025, which unsurprisingly caused prices to slump by almost half over the course of last year and the first part of 2026.That is why the government is searching for the most effective way of hitting the brakes without generating the sort of market disruption caused by Congo's cobalt export quota system.CHINESE DEPENDENCYChina has become increasingly reliant on Guinea for bauxite to feed its huge aluminium production sector.Imports of Guinean material mushroomed from just 334,000 tons in 2015 to 149 million tons in 2025, by which point they accounted for 74% of all bauxite imports.China has its own bauxite reserves but they've been depleted by decades of mining and are lower quality than those in Guinea.Moreover, the country has massively expanded its aluminium smelting capacity this...
