Iron Ore Lump Premium Price Assessment Explained

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.

Decrepitation of lump iron ores

Lump ore is one of the key ferrous materials used in the blast furnace ironmaking process, typically accounting for 5–25 per cent of the blast furnace ferrous burden. Like other ferrous materials, the characteristics of lump ore have an important impact on stable operation and productivity of a blast furnace. As the cold burden lands Get price

MIDREX Process

The shaft furnace is where iron ore is converted to metallic. Iron oxide, in pellet or lump form, is introduced through a proportioning hopper at the top of the shaft furnace. As the iron ore descends through the furnace by gravity flow, it is heated, and the oxygen is removed from the iron ore (reduction) by counterflowing gases that have a high H and CO content.

Direct reduced iron

Process Direct reduction processes can be divided roughly into two categories: gas-based, and coal-based. In both cases, the objective of the process is to drive off the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1,200 C (2,190 F)).

The use of lump ore or pellets also dispenses with the need for sinter plants. All metallurgical work is carried out in two separate process reactors - the reduction shaft and the melter gasifier. Lump ore, sinter, pellets or a mixture are charged into a reduction shaft where they are reduced to direct-reduced iron (DRI) by a reduction gas. Get price
