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). The purpose of the sintering process is manufacturing a product with the suitable characteristics (thermal, mechanical, physical and chemical) to be fed to the blast furnace.
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 processes, including …

Iron ore powder agglomeration is the basis for blast furnace ironmaking and is the processing work in between ore crushing, ore grinding separation, and steelmaking. Its purpose is to provide high-quality furnace burden for steelmaking. It is …
A lot of typological categories of iron ores and different ore blends can be used in the industrial processes of agglomeration and reduction. The ore quality variability is continuously changing. Besides, little consideration is being today to microstructural, mineralogical and " granulochemical " characteristics.
Abstract. The iron and steelmaking industry is actively seeking to reduce its overall carbon footprint with major research and investment directed towards fossil fuel-free steelmaking. In this paper, we present a novel iron ore agglomeration process that produces a Lime Magnetite Pellet (LMP) feed using concentrated solar flux as the …
ABSTRACT. The Chapter describes the quality parameters of pellets affecting the iron-making process and their dependence on the influencing variables. Their interrelationship with bonding in pellets and their textural characteristics are described. The influencing variables—process related, such as ore characteristics in terms of fineness and ...

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 …
There are four types of agglomerating processes which have been developed (Fig 1). They are (i) briquetting, (ii) nodulizing, (iii) sintering, and (iv) pelletizing. Fig 1 Agglomeration processes. Briquetting is the simplest and earliest applied process. Fine grained iron ores are pressed in to pillow shaped briquettes with the addition of …

Iron Ore Agglomeration Tests. All lab tests are designed around the distinct qualities of each material, and thus the sample's characteristics should be acknowledged prior to testing. Overall, iron ore is: Heavy. Abrasive. Dusty / easily wind-blown. Varying in composition (some samples contain more clay than others).
