Estimating the lump to fines composition split in iron ore

have different lump algorithms. Some ore geotypes give a greater percentage of lump, or show a greater lump to fines composition difference than do other types of ore. Some geotypes even tend to split according to a “reverse algorithm”, with the lump component being lower in iron and higher in silica and alumina than is the fines component.

Iron processing Ores Britannica

Crushed ore is divided into various fractions by passing it over sieves through which undersized material falls. In this way, lump or rubble ore (7 to 25 millimetres in size) is separated from the fines (less than 7 millimetres). If the lump ore is of the appropriate quality, it can be charged to the blast furnace without any further processing.
