The Relationship Between Mining and Sintering. Sinter is the primary feed material for making iron in a blast furnace, and we have previously written about sintering and how it is a step between mining ore and steelmaking. 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 ...

Iron Production Iron is produced in blast furnaces by the reduction of iron bearing materials with a hot gas. The large, refractory lined furnace is charged through its top with iron as ore, pellets, and/or sinter; flux as limestone, dolomite, and sinter; and coke for fuel. Iron oxides, coke and fluxes react with the

Abstract. Sintering is the most economic and widely used agglomeration process to prepare iron ore fines for blast furnace use. In this chapter, the sintering process is first described to identify the key steps of the process, that is, granulation and thermal densification. Discussion is then focused on the effect of the chemical, physical ...

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 highgrade iron ore sources has made necessary the utilization of concentration processes with the purpose of enriching the iron ore.

The process of sintering begins with the preparation of the raw materials consisting of iron ore fines, fluxes, inplant 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.

The results showed the possibility of using selective agglomeration to separate iron ore and apatite. The assays were applied to a concentrate obtained by jigging. The sample was ground to a particle size smaller than 400 meshes, to ensure release of the apatite. ... The agglomeration process was performed in a ball mill, in which conditioners ...

Currently, all available technologies require agglomeration, like pelletizing to produce DRI or HBI. An additional challenge steel producers face, is the reduced quality of iron ore, resulting in the need to beneficiate the iron ores. In order to progress to a CO2free steel production, a process using mainly H2 is most desirable.
