The work discussed a technology for iron ore agglomeration, where a mixed charge was humidified up to 6–10% with a pulp containing bentonite with a particle size of no more than 0.1mm and consumption of 2–18 kg/t. This resulted in an increased impact strength of the obtained agglomerate and its reduced resistance to abrasion.

Cold bonding is a low-temperature alternative to heat induration. Pellets can be cold bonded using lime, cement, sponge iron powder, and organic materials such as starch and flour. Cold bonding consumes less energy than heat induration, and has found favor for bonding self-reducing pellets and for refractory ores that are difficult to heat-treat.

Amongst various processes used in agglomeration, sintering and pelletization are widely used in the iron ore industries. About 70% of the blast furnace feed is reporting from the sintering processes. The objective of iron ore agglomeration is to generate a suitable product of granules in terms of thermal, mechanical, physical, and …

Pelletizing of iron ore is a method of Swedish origin, patented in 1912 by AG Andersson (Yamaguchi et al., 2010). The process was developed in the USA in the 1940s, and the first commercial plant started operation in Babbitt, Minnesota in 1952. The first iron ore pellet plant of the grate-kiln type was established at Humboldt Mine, …

Agglomeration of iron ores is the iron ore pre-treatment process in which the powdery iron ore that cannot be directly fed into a blast furnace experiences high-temperature solidification by sintering process and pelletizing process or low-temperature solidification by pelletizing process and briquetting process to generate the rich ore

Organic binders of iron ore pellets were widely investigated in past decades because they do not contaminate the product. This paper mainly involves the functions and molecular structure of ideal organic binders for iron ore pelletization based on fundamental principles of molecular design, interface chemistry, polymer science as …

Until the 1950s of the last century, the oxidized iron ores that were loaded into the blast furnace had granulometries within 10 and 120 mm. However, the depletion of high-grade iron ore sources has made necessary the utilization of concentration processes with the purpose of enriching the iron ore. Because of these processes, a fine …

Agglomeration of iron ores is the iron ore pretreatment process in which the powdery iron ore that cannot be directly fed into a blast furnace experiences high …

This is a challenging problem because iron ore pellets are a complex product of an agglomeration process which is typically controlled only to the extent that is necessary to form a quality ...

A passion for pelletizing and consideration of the entire process chain from start to finish are fundamental to innovative pelletizing-plant solutions. Raw-material testing, mathematical simulation, 3D planning, and process automation are key elements Primetals Technologies brings with its passion for innovation to the iron and steel industry.

The constant demand for iron ore leads to the need to mine even low-grade deposits. The diminished quality of natural resources is countered by economic, ecological, and technological restrictions that require the processing of the extracted iron ore. An enrichment of iron ore can be achieved by separating unwanted components. This …

Agglomeration of Iron Ores covers in considerable detail both the sintering and pelletising of iron ore fines and concentrates that are generated along with lump ore in iron ore mines around the world, either naturally or after upgrading in a beneficiation process. The book is devoted to a detailed treatise of the sintering and pelletising of the raw materials in …
