Iron Ore Sintering: Raw Materials and Granulation ...

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. This process is widely studied and researched in the iron and steelmaking industry.

Binders to Optimise Iron Ore Granulation for Future

2021-1-31  Granulation is the critical first stage of the ironmaking process for Australian fine iron ore. The addition of binders such as burnt or hydrated lime can enhance the granulation process, but the impact of varying properties of the binders is poorly understood. Work with industry partners to study this important phenomena.

The determination of optimum granulation moisture

The most common agglomeration process in iron and steelmaking is sintering. The process requires the use of iron oxide ores or concentrate mixtures, limestone and dolomite as fluxes and coke as fuel in order to produce the required melt at elevated temperatures to cause permanent bonding of particles. Prior to sintering, granulation of the mixed feed is required to effectively cause temporal ...
