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

2014-5-13 · 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.
