In view of decreasing availability of high-quality raw materials, the agglomeration of fine and ultra-fine iron ores becomes increasingly important to meet requirements of BF and DR plants. Primetals Technologies' comprehensive technological expertise on the entire metallurgical process chain is the basis for tailor-made sinter and pellet ...
Iron Ore Agglomeration Technologies. Until the 1950s of the last century, the oxidized iron ores that were loaded into the blast furnace had granulometries within 10 and 120 mm. However, the depletion of high-grade iron ore sources has made necessary the utilization of concentration processes with the purpose of enriching the iron ore.
This book focuses on agglomeration, or the size enlargement process, of iron ores. This process sits at the interface of mineral processing and extractive metallurgy. The book begins with a discussion of raw materials preparation and the beneficiation process. It then describes fundamental principles of the sintering and pelletization …
Pelletization is an agglomeration process of iron ore concentrates with a granulometry lower than 150 μ m and low concentration of impurities [10, 11]. This iron ore is mixed with water,
The mechanisms of agglomeration and defluidization and fluidization characteristic of iron oxide particles were investigated based on the theory of surface diffusion, interface reaction, surface nano/microeffect, and phase transformation. Moreover, a mathematical model was developed to predict the high-temperature defluidization …
Sintering is a thermal agglomeration process that is applied to a mixture of iron ore fines, recycled ironmaking products, fluxes, slag-forming agents and solid fuel (coke).
