This paper critically reviews published research on silico-ferrite of calcium and aluminum
('SFCA') phases, the major bonding phases found in modern iron ore sinters. In particular …

Complex silico-ferrites of calcium and aluminium (low-Fe form, denoted as SFCA; and high-
Fe, low-Si form, denoted as SFCA-I) constitute up to 50 vol pct of the mineral composition of …

In industrial iron ore sintering, the raw materials are heated in a reducing atmo_sphere and
then cooled under an oxidizing atmosphere. The sinter mainly contains hcrnatite, magnetite …

Macroscopic phenomena, such as fracture, corrosion, and degradation of materials, are
associated with various reactions which progress heterogeneously. Thus, material …

A range of iron ores were used in varying proportions to prepare 28 different ore mixtures.
Each mixture was classified according to its granulation index and sintered in a pilot plant …

In the iron ore industry significant emphasis is placed throughout the mining process on
meeting chemical composition specifications for the export of fine ores. However, little has …

Owing to the depletion of world lump iron ore stocks, pre-treated agglomerates of fine ores
are making up a growing proportion of blast-furnace feedstock (∼ 80%). These …

The physical properties of iron ore sinter are largely influenced by raw material properties, in
particular the bulk ore composition and its associated mineralogy. The levels of Fe, SiO2 …

Quenching experiments have been performed to investigate the thermal stability, solid
solution limits, and selected phase relationships of SFC (silico-ferrite of calcium) within the …

The ore mixture granulation process is described and the granulation fitness of a series of
iron ores forming part of the mixture is studied. Good granulation and control of the …
