Sinter Quality and Process of Sintering Iron Ores Ispat

21/11/2014· Sinter Quality and Process of Sintering Iron Ores. Sinter is normally the major component of the blast furnace (BF) charge burden. Sinter consists of many mineral phases produced during process of sintering of iron ores. The quality and properties of sinter are dependent on the mineral structure of sinter. However, since the sintering conditions are usually not uniform throughout the sinter

Minerals Special Issue : Mineralogy of Iron Ore Sinters

Iron ore sintering is a high temperature process which converts iron ore fines (<6–8 mm in size, too small for direct feed into the blast furnace) into larger agglomerates containing bonding phases, unmelted nuclei and pores. The sinter must possess the chemical, physical, metallurgical and gas permeability characteristics required for efficient blast furnace operation and these are

Recent advances in iron ore sintering: Mineral Processing

Corresponding to the changes in the availability of iron ore resources, the amount of impurities in iron ore has been slowly increasing. Some of these impurities have been found to have deleterious impacts on sinter quality and sintering performance. In the meantime, an increasing number of large blast furnaces with inner volumes of more than 5000 m

Evaluation of sintering behaviour based on ore

New pretreatment and sintering technologies are therefore required to tackle the gradual change in the quality of iron ore fines. In the sintering process, iron ore fines are first granulated with fluxes such as limestone and coke breeze, and are then loaded and fired in a sinter machine. Sinter productivity and quality are heavily influenced by the reactions occurring in the sintering bed
