The Platts lump premium assessments reflect the tradable price of iron ore lump brands that are most widely traded in the market. Most commonly, Platts observes spot lump transactions being concluded as a floating price premium over the monthly average of IODEX assessments, which is how the assessment is directly presented on a US dollar per dry metric ton unit CFR Qingdao basis.

The direct reduction process uses pelletized iron ore or natural "lump" ore. One exception is the fluidized bed process which requires sized iron ore particles. The direct reduction process can use natural gas contaminated with inert gases, avoiding the need to remove these gases for other use.
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.
