Since the processes use only iron ore fines and non coking-coal, FASTMET and FASMELT are expected to be the iron making processes of the 21st century, especially with the current roaring prices for lump-ore and coking-coal. 3. ITmk3R process The ITmk3 separates "nugget iron" and slag directly from the iron ore fines and pulverized coal.
have different lump algorithms. Some ore geotypes give a greater percentage of lump, or show a greater lump to fines composition difference than do other types of ore. Some geotypes even tend to split according to a "reverse algorithm", with the lump component being lower in iron and higher in silica and alumina than is the fines component.
A blast furnace (BF) is the most common process for hot metal production in the world. The BF is charged with metallurgical coke and iron-bearing materials separately, which leads to a lay- ered structure.The iron-bearing materials consist ofironorepel- lets, lump ore, and sinter. When the charge material descends, it is reduced by CO and H 2.
blending of lumps and fine of iron ore is a process. Ore Blending - Metallurgist and Mineral Processing Engineer Blending here would provide a uniform mineral content which would aid in fine tuning the extraction process to attain maximum output 2 The presence of an undesirable type of ore that could be processed but which would cause a reduction in overall output if it …
Process Processing of the ore ranges from simple crushing and screening to a standard size, through to processes that beneficiate or upgrade the quality of the iron ore products. This is done by physical processes, which remove impurities by differences in particle density or size gravity or size separation. Processing may be wet or dry.
Iron ores are used in the form of lump ores, sinter and pellets. Lump ores are natural useable coarse grained ores extracted at iron ores mines. Preparation and enrichment processes undertaken at the iron ore mines to increase the iron content, however, result in increasingly fine grained ores that must be granulated.

Trading in high-grade Australian iron ore lump has increased in both the seaborne and portside market since December 2021, amid supply tightness and ongoing sintering production cuts in north China, sources told Fastmakets on Wednesday January 5.
for beneficiation of Indian Iron Ores is the Jigging process – using an air pulsated BATAC jig. BATAC JIG BATAC Jig Technology has been successfully introduced to the iron ore industry for up gradation of interlocked iron ores, lump ores as well as sinter fines, which require high separation densities to obtain marketable concentrate grades.
The Platts spot iron ore lump premium assessment (IOCLP00) is of the premium a lump cargo commands over the price of fines as defined by the Platts 62% Fe Iron Ore Index, or IODEX. This premium is assessed on a US dollar per dry metric ton unit CFR Qingdao basis, which is applied over the IODEX assessments.

Calibrated lumps for DRI Iron production through DRI (Direct Reduced Iron) route is a very controlled process which requires the Iron-ore feed to be in the range of 5mm – 18mm. Presence of particles finer than this creates problems in the kiln in the form of accretions in the kiln walls and also higher consumption of coal fines.
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.
