Sintering: A Step Between Mining Iron Ore and Steelmaking. The USGS defines iron ore as a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3). It's a major ingredient in steel.

A method for producing a sintered ore (50a) which comprises forming, on the surface of a nucleus particle (51) containing an iron ore, a first coating layer (52) using an iron-containing substance andoptionally an SiO2-containing material, and subsequently a second coating layer (53) using limestone and a solid fuel based material, to prepare a granulated particle (50), and then sintering the ...

iron ore. His process involved grinding taconite to remove gangues and upgrading the iron ore (i.e., an ore beneficiation process). The resultant high-grade ore is in the form of fine particles, as small as 0.1mm or less, which are not suitable for sintering. This issue led to the use of pelletizing. Pelletizing plants are expected to play an

Thus, sintering mechanisms responsible during the initial stages are only important for iron ore sintering. Wynnyckyj and Fahidy[ 36 ] made an early in-road by studying the sintering kinetics of pure hematite reagent powder and commercial magnetite concentrate in the form of briquettes under isothermal conditions.

The sintering of the hematite–ilmenite ore blends has several challenges, which include the formation of perovskite. The sintering behavior of a hematite–ilmenite ore sinter blend was investigated in 75 vol% N 2, 24 vol% CO 2, and 1 vol% CO in the temperature range of 1373 to 1523 K. Phase development and distribution of metallic elements ...

Accordingly, the suitability of recycling this RM in the sintering process of Egyptian iron ore was studied.
