During the iron ore sintering process, the loose raw materials, mixtures of fine ore, limestone flux and coke breeze, are converted into a porous but physically strong cake, which is generally composed of four main phases iron oxides, ferrites, most of which are a complex silico-ferrite of calcium and aluminum SFCA, glasses and dicalcium silicate.
2020-9-24ensp0183enspIron ore sintering is a complex thermo-chemical process and the qualities of sinters being produced affect the blast furnace performances in terms of fuel consumption, smooth operation, and rate of production. Nath et al., 2004.
Due to ongoing demand and increasing depletion of high-grade iron ore resources from large deposits, Australian iron ore producers are developing smaller size deposits to maintain current export levels. The iron grade, mineralogy, chemical and physical characteristics of iron ore fines being mined from different deposits vary considerably.
The main effect on iron ore mineralization performance in the sintering process is the grain size of raw material and chemical composition. The results show that -0.5mm particles can mineralize, but 0.5mm particles remain a nucleus in sinter. This paper analyses the effect of the chemical composition on mineralization characteristics of liquid production.

IRON ORE DAILY Easing October sintering restrictions prompt seaborne price support Seaborne iron ore prices were up on Tuesday September 29 amid the easing of sintering restrictions in Tangshan over October, trade sources said. Fastmarkets iron ore indices 62 Fe fines, cfr Qingdao 117.61 per tonne, up 1.46 per tonne.
The reduction kinetics tests of Shougang sintering iron ores were performed from 1173 to 1373 K with 100CO by thermogravimetric analysis,from which the values of reduction reaction apparent activation energy were determined.
History of sintering of iron ore. Middle of nineteenth century, small sintering pot used to be constructed in the copper mining in England. The origin of sintering process goes back to 1887 when F. Haberlein and T. Huntington of England invented the process of agglomeration for sintering of sulphide ores.
The iron ore used presents a low MgO content 0.01 and a high Al2O3 content 2.99. It was seen that raising the MgO content in the sinter, from 1.4 to 2.6, increased the FeO content and decreased productivity and the RI, RDI and TI indices 13.
With rising iron ore prices having eroded steel margins recently, Chinese steelmakers are closely monitoring the spread between the two categories to optimize sintering costs. Prices of seaborne cargoes have also shown similar trends.
Silico-ferrite of calcium and aluminum SFCA is one of the most commonly-produced phases in fluxed iron-ore sintering, and has long been regarded as an important bonding phase in industrial sinters.
