Iron Ore Sinter an overview ScienceDirect Topics

With the rapid change in iron ore supplies and composition, steel mills now have to adjust the composition of the ore mixture to their sinter plants more frequently than ever before. Hence, different scales of test methods have been developed to help sinter plants evaluate new ore types and ore blends in order to optimize their ore mixtures.

Ore Sinter an overview ScienceDirect Topics

For example, in blast furnace iron making, Fig. 5.1, iron oxide in the form of lumpy ore, sinter or pellet along with coke and limestone, are charged on the top of the furnace continuously. The charge slowly moves down and hot reducing gases produced by burning of coke in front of tuyeres move up through the bed of solids and finally escape

2021-3-3  During the iron ore sintering process, two types of particles are present in the sinter bed: (1) fines, which are actively taking part in melting and the formation of secondary phases, and (2) coarse ores, which are partially interacting with the surrounding melt. The quality of the final sinter is particularly determined by the secondary phases and their bonding ability.

Properties and End-Use Functionality of Iron Ore

Unlike iron ore sinter and pellets which are manufactured from iron ore fines and or concentrate, lump can be directly charged to the furnace without any pre-processing. As a result, lump has an inherently higher value compared with fines due to the avoidance of agglomeration costs. Australia is a significant producer of iron ore lump.
