The US$2.6 billion project, a joint venture between Fortescue Metals Group subsidiary FMG Magnetite and Formosa Steel, was green-lit earlier this year. With premium magnetite iron ore reserves, once fully operational, the mine is expected to produce 22 ...
Enduron® high pressure grinding rolls (HPGR) provide a flexible comminution solution with the operational bandwidth to process different types of ore throughout the life of a mine. It …
The HPGR advantages for the iron ore pelletizing are pellet feed moisture reduction, lower energy consumption, and capability to adjust PSD after dewatering instead of at the beneficiation unit [].Nunes et al. [] demonstrated that a better pellet feed PSD (where % < 325# fraction is higher than 90%) improves considerably the physical green pellet quality.
Lean magnetite resources in China are characterized by low iron grade, fine embedded particle size, complex composition, etc., which can only be utilized through complex beneficiation processes [1,2,3].With the increasingly serious problems of low-grade, fine iron minerals, and difficult-to-treat ore properties, the required particle size of ore grinding products …
How-ever, there are a few notable examples where HPGRs are used for coarse iron ore grinding – in Chile, Mauritania and the USA. The first large scale attempt at applying HPGRs to harder …

An iron ore concentrate sample was ground separately in a pilot-scale HPGR mill in multiple passes and a dry open-circuit ball mill to increase the specific surface area of particles.
We have now launched HPGRs at Sections 2 and 3, completing the upgrade of the entire beneficiation plant. This will enable us to increase primary iron ore processing up to 37 million mt/y, up by 5 million mt/y in 2013, and become self-sufficient in iron ore feedstock." Each HPGR unit replaced two conventional crushers.
