World resources are estimated to be greater than 800 billion tons of crude ore containing more than 230 billion tons of iron. The only source of primary iron is iron ore, but before all that iron ore can be turned into steel, it must go through the sintering process. Sinter is the primary feed material for making iron and steel in a blast furnace.

ABSTRACT. Sintering is an agglomeration process that fuses iron ore fines, fluxes, recycled products, slag-forming elements and coke. The purpose of sintering is to obtain a product with suitable composition, quality and granulometry to be used as burden material in the blast furnace.
Sinter plants currently have to use many types of ores with different properties owing to the great demand for iron ores, which was driven by the massive growth in Chinese iron and steel industry. On the other hand, the development of iron ore mines is limited and the quality of iron ores is in a tendency of deterioration.
Specular iron ores are medium grade iron ores suitable to use in agglomeration process. However, due to their hard texture, undesirable particle size and shape, poor assimilation performance and low reactivity at high temperature, its uses in agglomeration is very limited and restricted to almost 3-10% at most of the plant. In the …
