World resources are estimated to be greater than 800 billion tons of crude ore containing more than 230 billion tons of iron. 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 sintering process. Sinter is the primary feed material for making iron and steel in a blast furnace.
10%Mill scale is a valuable ferrous raw material, containing 65 to 70 pct iron and is often recycled through the sintering process. During iron ore sintering, iron ore fines are mixed with limestone and coke breeze. The combustion of coke breeze supplies the necessary heat to achieve partial melting and reaction of the raw materials.
Optimal Scheduling of Iron Ore Discharge and Blending. Jul 01 1998 The ore treatment process with respect to discharge and blending ore creation is shown in Fig.1. Live Chat; Ore blending ratio optimisation for sintering based on. The iron ore blend for sintering depends to a great extent on ore properties.
The scheme of the iron ore sintering process is represented by Fig. 5. Sinter mixture contains iron ore, solid fuel (usually coke breeze), flux and some additives (e.g. solid wastes like BOF slag, gas cleaning dust and sludge etc.). The mixture is granulated with the addition of moisture and loaded to the travelling grate of the sintering plant.
According to the U.S. Environmental Protection Agency, the sintering process converts fine-sized raw materials, including iron ore, coke breeze, limestone, mill scale, and flue dust, into an agglomerated product, sinter, of suitable size for charging into the blast furnace.
Sintering is a thermal process (carried out at 1300 deg C to 1400 deg C) by which a mixture of iron ore, return fines, recycled products of the steel plant industry (such as mill scale, blast furnace dusts, etc.), slag forming …
Iron-rich (65 to 70 pct total Fe) mill scale generated during processing by steel mills can be recycled by using it as a ferrous raw material in the sintering process.
Ore-A was limonite ore from Australia, Ore-B was hematite ore from Brazil, Ore-C was blending ore from a Chinese steel mill. Table 1 shows the chemical composition of the fluxes and ores used in this study. Table 2 shows particle size of dolomite comparing with other fluxes in the sinter pot tests. In addition, 3 different particle size ...
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 and the key steps of the sintering process, namely, granulation and thermal densification, are identified. Discussion is then focused on the effect of the chemical ...
The present paper reviews the sintering process that the mixture follows, once granulated, when is loaded onto the sinter strand. There, the …
Some mills are also using larger volumes of more expensive lump ore to mix with fines to save on the sintering process, which creates a product that can be used in a blast furnace but is a major ...

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, and ...
The iron ore sintering process prepares fine iron the ores for the blast furnace process. Sinter plants agglomerate iron ore fines with other fine materials at high temperature in a mix bed to create a product that can be used in a blast furnace. Main feed into a sinter plant is base mix, which consists of iron ore fines, coke fines and flux ...
sintering is a thermal process (carried out at 1300 deg c to 1400 deg c) by which a mixture of iron ore, return fines, recycled products of the steel plant industry (such as mill scale, blast furnace dusts, etc.), slag forming elements, fluxes and coke fines are agglomerated in a sinter plant with the purpose of manufacturing a sintered product …
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).
