Mar 09, 2013· The process of sintering begins with the preparation of the raw materials consisting of iron ore fines, fluxes, in-plant metallurgical waste materials, fuel and return fines of the sinter plant. These materials are mixed in a rotating pelletizing drum and water is added in order to reach proper agglomeration of the raw materials mix.
Jun 13, 2017· Some of the oxidized ore contains no clayey material, and crushing it generates very few fines. Only 6 pct of the material is minus 200 mesh. Consequently, it does not require a cement binder for agglomeration. This portion of the ore is agglomerated with cyanide solution to start the leaching process during heap building.
Similarly, production of primary iron from iron ore is critically dependent on agglomeration. Concentration of iron oxide minerals requires grinding to very fine particle sizes, frequently smaller than 25 µm, in order to liberate and separate the iron oxides from the silicate gangue.

Agglomeration of fine grained minerals is widely employed in the placement of bentonite or lime binders in iron ore pelletization, The organic binder burns during the induration process (up to 1350 °C), leaving a higher porosity of the pellet (2 – 3% higher).
The BF/BOF process typically involves five parts: coking, iron ore agglomeration, blast furnace (BF), basic oxygen furnace (BOF), and manufacturing the final steel product (rolling, casting, etc.).3 An overview of the BF/BOF process for steelmaking is shown in Figure 1-1. The initial part of the process, coking, iron ore agglomeration, and

Apr 29, 2016· 42 P a g e MODULE-3 AGGLOMERATION OF ORE What is agglomeration: agglomeration is a technique by which the fine iron ores are converted into lumps. Why agglomeration is required : 1- use of fine iron ore in iron making , since during communiation of iron ore some of the ores are converted into fines.
A process for improving the compressive strength of iron ore agglomerates, such as pellets or briquettes, used as a feed to an iron blast furnace, in which the particulate iron ore is treated, either before or after agglomeration with sufficient liquid or gaseous iron pentacarbonyl to provide about 2-5% carbonyl iron on the surfaces of the iron ore particles, following decomposition of the
Material and heat balance of the process of iron ore fines agglomeration (per 100 kg of agglomerate) are pre-sented in the tables 1 and 2.
