Lump ore | mining | Britannica
Other articles where Lump ore is discussed: iron processing: Lumps and fines: Asmined iron ore contains lumps of varying size, the biggest being more than 1 metre (40 inches) across and the smallest about 1 millimetre (004 inch) The blast furnace, however, requires lumps between 7 and 25 millimetres, so the ore mustCrushed 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 processingIron processing Ores | Britannica

Schematic of a typical lump iron ore production process Typically, the runofmine iron ore will undergo primary crushing, which is normally carried out in jaw or gyratory crushers Afterward, secondary crushing is done using cone crushers Other types of crushers can be used depending on the hardness and grindability of the oreThe 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 basisIron Ore Lump Premium Price Assessment Explained | S&P

Lump ore can bypass this process and be charged directly into the furnace, as can pellets, and both command an associated price premium Most steel mills use a blend of different grades of ore, and a mix of sinter, lumps and fines, but the quality requirements depend on the circumstances and availabilityAt the last round of iron ore price negotiations, BHP Billiton secured prices of $14777 a tonne and $20598 a tonne respectively for fines and lump iron oreWhy fines and lumps make a difference | Adelaide Now
