Relating Iron Ore Lump and Fines Grade Split to Ore Type

When iron ore is crushed and split into lump and fines components, there are systematic differences between the lump and fines grades. Generally the lump product is richer in iron and lower in the other minerals, compared to the fines product. The grade differences between lump and fines, together with the lump percentage, are referred to as the lump algorithm'.

Understanding the high-grade iron ore market

Whether referring to naturally iron-rich DSO fines or lump or artificially enriched beneficiated concentrate, one of the key elements that determines value is its chemical composition, or ‘grade’. As a rule of thumb, a higher iron content will generally mean a higher market value for the ore since iron units are what a steel mill wants.
