to produce a pilot lot of metalized pellets we used iron-ore concentrate (by abagursk ore-processing plant, city of novokuznetsk), hematite-magnetite ore (by tashtagol ore mine), and low-caking coal of cc grade (by bachatsk coal mine). table 2 shows properties of the materials in use. table 2. properties of the materials in use material,iron ore pelletizing process: an overview | intechopen,the iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. however, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed. the fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. this chapter shows the status of the pelletizing process
beneficiation plants for upgrading iron ore and pelletizing plants for agglomerating. the iron ore fines cannot be the pellets are approximately spherical lumps formed by this process with the help of water and binder, on subsequent induration at 1300°c [6, 8, 9, 13, 15 - 20]. the particle size of iron ore concentrate (pellet feed,the krupp sponge iron process production and utilisation,developed the krupp sponge iron process which is capable of reducing high-fe lump ore as well as fine ore and concentrates into metal-lized products, using in the main solid fuels (2-9). essential features of the process fig. 1 shows the two variants of the process, one using lump ore and the other fine ore or
blast furnaces 5 and 6 currently operate on the site to produce iron from a mixture of ore lumps, pellets, sinter, coke, fluxes and other minor additives. iron ore is the principal ingredient and is fed to the blast furnaces as either lumps or fines. unprocessed fine ore tends to inhibit gas movement through the furnace and is carried out of the furnace by the upward flowing gases so all fines are,kobelco pelletizing process,include iron scrap, reduced iron pellets and reduced iron briquettes. sintered ore is made by partially melting and sintering coarse iron ore 1 to 3mm in size into products having a size of 15 to 30mm. the sintering process uses the combustion heat of coke breeze (fuel). pellets are made from iron ore
