Included in this article also is a discussion of the mining of iron and of its preparation for smelting. Iron (Fe) is a relatively dense metal with a silvery white appearance and distinctive
Caraj225;s Mine, the worlds 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
Iron ore pellets and Pelletizing processes. Pelletizing is a process that involves mixing very finely ground particles of iron ore fines of size less than 200 mesh with additives like bentonite and then shaping them into oval/spherical lumps of 8 16 mm in diameter by a pelletizer and hardening the balls by firing with a fuel.
