composition, not only in iron, but also in phosphorus, silica and alumina. The customer blast furnaces are tuned to receive ore of the agreed target composition. Issues relating to quality control in iron ore production are discussed in [1,2]. When ore is crushed and split into lump and fines components, there are

Relating Iron Ore Lump and Fines Grade Split to Ore Type

When iron ore is crushed and split into lump and fines components, there are systematic differences between the lump and fines grades.

Estimating the lump to fines composition split in iron …

When ore is crushed and split into lump and fines components, there are systematic differences between the lump and fines compositions. The lump component is usually (but not always) richer in iron, and with less silica and alumina, than the fines product.

Study of Mineralogy and Metallurgical Properties of Lump …

The ironmaking process in blast furnaces using iron lumps is an energy-efficient and low-carbon initiative that helps lower the cost of the ironmaking process. The physical and chemical properties of raw materials, process mineralogy, and metallurgical properties of three Malaysian iron ore lumps were researched in this paper, with the goal of showing the …

Iron processing

Lumps and fines Crushing. As-mined iron ore contains lumps of varying size, the biggest being more than 1 metre (40 inches) across and the smallest about 1 millimetre (0.04 inch). The blast furnace, however, requires lumps between 7 and 25 millimetres, so the ore must be crushed to reduce the maximum particle size. Crushed ore is divided into ...

Understanding the high-grade iron ore market

Iron ore lump and sinter fines are examples of DSOs, which are mined predominantly from areas such as Australia's Pilbara and Brazil's Carajas regions, where geological processes have led to iron content levels of between 55% and 65%. These ore types require little processing beyond crushing and screening before being 'directly-shipped ...

The Direct Reduction of Iron. Thomas Battle, ... James McClelland, in Treatise on Process Metallurgy: Industrial Processes, 2014. 1.2.2.2 Agglomeration of Iron Ore. The three major forms of iron used in ironmaking are pellets, lump, and sinter. The major change in the past 50 years has been the development of cost-effective pelletization technology allowing pellets to be a …

Iron ore fines

Description: Iron ore fines come from the natural raw iron ore through the process of mining, crushing and screening, where the iron ore is separated into lumps and fines. Iron ore is done in this fashion so that it can be used for the iron/steel …

From Iron Ore to Crude Steel: Mass Flows Associated with Lump…

If lump production is 30% of the pellet production, for example, the total iron ore flow from lump ore (M l1 + M l2) is only 0.12 t, which avoids 0.18 t of mined rock, compared to a base case requirement of 6.8 t for the production of pellets with 1 t of iron. 2.1.3.

Iron ore lumps: size 10-40mm Iron ore fines: Granular size of up to 10 mm for up to 90% of the cargo. While lumps are crushed to 5-20mm size in crusher, normally 30% fines (waste) will be generated.

Iron ore

The crushed ore is sorted over screens and resized to different specifications, such as lump and fines products. Once the iron ore is processed, a stacker builds a stockpile in the stockyards. When ready for transportation, a reclaimer picks up the ore from the stockpiles and conveys it to train load out facilities.
