Iron ore is the world's most traded bulk commodity after crude oil. Global exports reached approximately 1.6 billion tonnes in 2024, up 2% year-on-year. Seaborne iron ore trade exceeded 1.7 billion metric tons, with China absorbing roughly 75% of global import value.
| Country | Export Volume | Share of Global Exports |
|---|---|---|
| Australia | 866 million tonnes | 54.5% |
| Brazil | 390 million tonnes | 19.6% |
| South Africa | 61 million tonnes | 4.2% |
| Canada | 61 million tonnes | 4.2% |
China (1.27 billion tonnes seaborne imports), Japan, South Korea, Germany, and EU steel producers. Major miners: BHP, Rio Tinto, Vale, and Fortescue Metals Group collectively ship over 1 billion tonnes annually.
Iron ore is priced on Fe content (62% Fe CFR China benchmark), silica, alumina, and moisture. Premium lump ore commands higher prices for direct blast furnace charging; fines are used for sintering and pelletizing.

Bauxite is the primary aluminium ore, composed of gibbsite, boehmite, and diaspore aluminium hydroxides. Global mine production reached approximately 450 million metric tons in 2024. About 85% of bauxite is processed via the Bayer process to produce alumina for aluminium smelting.
| Country | Production (Mt) | Reserves |
|---|---|---|
| Guinea | 130 | 7.4 billion tonnes |
| Australia | 100 | 73.5 billion tonnes |
| China | 93 | 680 million tonnes |
| Brazil | 33 | 2.7 billion tonnes |
| Indonesia | 32 | 2.8 billion tonnes |
Metallurgical-grade bauxite typically contains 45-60% Al2O3, low silica (3-8% SiO2), and is found in tropical laterite deposits. Australia's Boddington and Weipa mines, and Guinea's Boké region, are among the world's largest high-grade sources. Pisolitic and oolitic bauxite textures indicate premium aluminium ore quality.
Global alumina production: ~142 million tonnes (2024). China (84 Mt), Australia (18 Mt), and Brazil (11 Mt) lead refining. World aluminium smelting consumes ~140 million tonnes of alumina annually.
