High Temperature Mineralization Behavior of Mixtures during Iron .
Introduction. Iron ore sintering is a heat treatment process for agglom- erating fine particles into larger lumps, which then serve as the major burden for blast furnace. The production of high- quality sinter is critical for efficient blast furnace operation. The quality and yield of sinter are determined to great extent by the.
Iron ore classification and the future of resource development .
The different textures have distinct physical properties and behaviours that will impact grade, crushing, processing, bulk handling, sintering (fine ore) and blast furnace (lump ore) behaviour. The increased prevalence of goethitic ore coming from Australia's mines means the need for a robust textural classification framework.

Iron oxide can be fed to the blast furnace in the form of raw ore (lump), pellets or sinter. . Sinter is produced by agglomerating fine ore, utilising coke or another.
What are the advantages and disadvantages of high silica in iron ore?
Tolerance to silica and alumina in iron ore depends on the process and ore size. Lump +6mm particles can be fed directly into the blast furnace while fines (generally -6mm) need to be agglomerated via sintering for example. The sintering process is sensitive the high alumina which causes increased melt phase viscosity.

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.
