blending of lumps and fine of iron ore is a process

iron ore blending process

After blending, the iron ore fines are exported from the facility for the Asian seaborne market. The closure is seen to be supportive for both iron ore prices and alumina differentials amid a tight supply situation given the existing volumes stuck at Teluk Rubiah and fewer cargoes coming out of Brazil during the rainy season, market sources said.

Estimating the lump to fines composition split in iron ore ...

Issues relating to quality control in iron ore production are discussed in [1,2]. When ore is crushed and split into lump and fines components, there are systematic differences between the lump and fines compositions. The lump component is usually (but not always) richer in iron, and with less silica and alumina, than the fines product.
