Microstructure and Minerals Evolution of Iron Ore Sinter

The mini-sintering method includes ore blending, briquetting, sintering, and cooling. Specifically, fine-grained iron ores within a size range of −5 mm were mixed with fluxes (limestone, quicklime, and dolomite), and then ground to a size under 0.074 mm and compressed into a standard pyrometric cone (20 mm in height and a side length of 5 mm).

the sinter. In the sintering process, the iron ore corresponds to the mixture of hematite, goethite and other gangue mineral typologies. However the goethite and gangue contents are relatively lower than the hematite, but the goethite + gangue to hematite ratio influences the reactivity during sintering. The minerals association in iron

Sinter plant Wikipedia

Sinter plants agglomerate iron ore fines (dust) with other fine materials at high temperature, to create a product that can be used in a blast furnace.The final product, a sinter, is a small, irregular nodule of iron mixed with small amounts of other minerals. The process, called sintering, causes the constituent materials to fuse to make a single porous mass with little change in the chemical

Moreover, the SiO 2 content in imported iron ores is relatively lower than that of the domestic iron ore concentrates, which helps to produce sinter with lower impurity levels. However, an excessively low SiO 2 content would lead to insufficient generation of SFCA (Quaternary compound of calcium ferrite containing silicate and alumina) under

Importance of Melt Generation and Properties in Iron Ore

In iron ore sintering, the blended particulate bed on the strand is partially melted in the flame front to form a three-phase solid-melt-gas mix. The presence of melt causes the mix to reshape, coalesce and aggregate into dense clusters. With the passing of the flame front, a solidified bed com-posed of identifiable large particles is obtained.
