Caraj s Mine, the world’s largest iron ore mine, is located in the state of Para in northern Brazil.Fully owned by Brazilian miner Vale (CVRD), it holds 7.2 billion metric tonnes of iron ore in proven and probable reserves. The Carajas region boasts the richest reserves and concentrations of iron ore anywhere in the world and was discovered entirely by accident in the late-1960s when a US.
The geological grade of the ore deposit is relatively high (about 50 ), but the ore body is thinner or has interlayers. The waste rock is mixed in during mining to dilute the ore. For this kind of ore, only crushing and no-grinding can be used so coarse-grained tailings are discarded through re-election to recover the geological grade.
Primary crusher, where it will proceed to undergo three crushing stages and two screening stages before the ore is fed onto the product stockyard (with an approximate total capacity inclusive of bulk-out stockpiles of 80,000t) via two radial stackers (one for lump product and one for fines product).
