Iron making blast furnace requires high air permeability during operation so the iron ore fines should be processed into iron ore pellets in the iron ore pelletizing plant in advance During the processing of high grade iron ores which don t need beneficiation many ore fines are generated which are usually regarded as waste
The mechanism of chemisorptions and compound molecule bridged linkage by organic complex bentonite to improve the pelletization of iron ore concentrates was demonstrated by the determination of X
Utilization of Pellet Fines in the Iron Ore Sintering Process Prusti et al [5 ] attempted to reuse iron oxide pellet nes by pelletization to produce quality pellets However the oxidized sintering machine It consists of a cylindrical bed a suc tion fan an exhaust pipe and a burning hood
Iron ore lump sinter and pellets comprise the main burden of modern blast furnaces However sinter and pellets are now the dominant blast furnace burden because the natural lump supply has declined dramatically due to depletion of the world s high grade competent iron ore resources
Bentonite is the traditionally used binder in iron ore pelletization However it consists of up to 85% silica and alumina which are undesired acidic gangue in iron making
The concentration of low grade iron ores is vital to the continued availability of iron and steel in our everyday lives Eisele and Kawatra 2003;Kawatra and Claremboux 2021a;Zhang et al 2021
Pelletization Pelletization is the most popular method of converting iron ore fines into agglomerates Early work on pelletization took place in Sweden but commercialization at large scale first occurred in the United States [13] In this case processing technologies for low grade taconite ores were needed due to exhaustion of the
The size fraction of iron ore fines prepared for pelletization is shown in Table 1 Chemical analysis of iron ore and fluxes including bentonite are shown in Tables 2 and 3 respectively The used coke fines of mm size contains 85% fix
The open pit mining method is the most used by Brazilian mining companies in the mining stage being remarkable at the beginning of the macro process of ore extraction ensuring that the iron ore
However the content of iron in ore deposits has deteriorated and low grade iron ore has been processed The fines Bentonite is a predominant binder used in iron ore pelletization However the presence of a high content of silica and alumina in bentonite is considered undesirable for ironmaking operations The balling equipment that
4 Need of pelletizing of Iron ores Configuration of Iron ore fines as tightly packed structure that restricts heat and air flow in blast furnace Utilization of iron ore fines of size even Extending the life of iron ore reserves of nation To improve Blast furnace performance Increase in blast furnace productivity Decrease in uses of blast furnace fuel/coke
During the process of iron ore pelletization and preparation of feed for DRI or reduction smelting processes around 3% of pellet fines less than 8 mm are generated as undesired product in the

Iron Ore Pellets Market Outlook from 2025 to 2035 Global sales of iron ore pellets stood at USD billion in 2024 The industry is further projected to exhibit a y o y growth of % in 2025 and reach USD billion in the same year and surging at a CAGR of % between 2025 and 2035 demand for the iron ore pellets is estimated to reach USD billion by 2035
The product pellets on size with a diameter of 16 mm are classified in the last quarter of the screen which is of gaps between 16 and 18 mm [2 3] from the oversize pellets with a diameter
Iron ore pellets can be made from beneficiated or run of mine iron ore fines History of pelletization The history of pellets began in 1912 when a Swede invented a pelletizing method balling equipment produces green balls from the pre wetted material prepared in the previous process The balling drum and the disc
Study and Implementation of Quality Improvement Techniques to Improve the Consistency in Cold Crushing Strength of Iron Ore Pellets Aditya Sarda1 Naik Nithesh1 Navneeth Krishna1 Tarun Shrivastva 2 and Arun Prabhu 1 1 Department of Mechanical Engineering Manipal Institute of Technology Manipal Karnataka India 2Quality Assurance
Evolution of binders for iron ore pelletizing Induration technologies Challenges and innovations in iron ore pelletizing 2 Pelletizing process and raw materials The iron ore is mined mostly from open pit deposits through mining operations and the raw product run of mine is subjected to mineral processing
1 IRON ORE PELLETIZING The main raw material in iron steel industry is iron ore Iron ores can be classified as high grade and low grade in terms of their Fe content High grade iron ores which can be used directly in the blast furnace to produce metallic iron are not abundant in earth s crust to supply the need of iron steel industry
