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'.

The price of DRgrade oxide pellets carries a premium. The reason for premium is primarily due to: Cost of beneficiation. Upgrading run of mine iron ore to DRgrade is expensive. Note: DRI manufacturers have been pushing for higher quality DRgrade pellets. Additional energy and investment costs for beneficiation technology.

Iron ore crushing. The extracted iron ore will be transported to the primary crusher. Oversized and wet ore will be sent to the ROM stockpile for pretreatment before it is sent to the primary crusher. Primary and secondary crushing followed by screening will result in lumps and fines sized between 32mm +8mm and 8mm respectively.

· Iron ores used in the steel industry must have some certain chemical properties including the amount of Fe(II), Fe(III), and the total Fe. In some geological studies, having an accurate level of Fe(II) and Fe(III) is essential for determining the petrology and mineralogy of an ore.[] Iron is found naturally in hybrid forms such as oxide, sulfide, carbonate, and silie.
