1.1.2 Sintering process Sintering of iron ore is a process [5,6,8] in which air is drawn down through a bed of raw mixture of iron ore, limestone, coke and other minor additives. The iron ore may be natural ore, which usually has a particle size up to 10mm, or concentrate which is very fine with a
Sinter Feed. The term Sinter Feed relates to iron ore which is too fine grained for use in a blast furnace in the current state. The fines are agglomerated in a sintering plant by adding a binding agent such as limestone, so they form larger particles.
Sinter is the primary feed material for making iron in a blast furnace. Sinter is created by mixing iron ore concentrate with several additives such as limestone and silica to control the chemistry and then igniting it at 1200°C in a continuous belt-fed furnace.
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.
Sintering process helps utilization of iron ore fines (0-10 mm) generated during iron ore mining operations; Sintering process helps in recycling all the iron, fuel and flux bearing waste materials in the steel plant. Sintering process utilizes by product gases of the steel plant.

Much of the theoretical work1-' has dealt with the constitution of sinter produced under widely varying conditions.
Iron ore sintering creates substantial off-gas volumes, and treating (PDF) Iron Ore Sintering: Process - ResearchGate. 2017-6-20 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).
Sintering of iron ore is a generic term which is used to describe the process whereby a sinter mix (raw mix or green mix) of iron ore fines, fluxes, fuel (coke breeze) and plant return fines (e.g. mill scale, blast furnace dust, and returned sinter fines etc.) are converted into a particular form of agglomerate.

Sintering is an agglomeration process that fuses iron ore fines, fluxes, recycled products, slag-forming elements and coke. The purpose of sintering is to obtain a product with suitable composition, quality and granulometry to be used as burden material in the blast furnace. This process is widely ...
Modeling Sintering Process of Iron Ore 25 Fig. 2. Thermal cycle of the materials in the sinter strand. Several attempts have been done to predict the final properties of the sinter product (Water et al. 1989, Kasai et al. 1989, 1991). The most important parameters are reducibility,

DSO is a sintering fines material. It is sold to steel mills and used as a feedstock in the production of sintered iron ore, which in turn is used as a feedstock for iron-making blast furnaces. It is in the blast furnace that the iron ore is converted to liquid hot metal. Iron ores are oxides that are rich in iron …
the sinter. In the sintering process, the iron ore corresponds to the mixture of hematite, goethite and other gangue mineral typologies. However the goethite and gangue contents are relatively lower than the hematite, but the goethite + gangue to hematite ratio influences the reactivity during sintering. The minerals association in iron
Dec 16, 2018· Iron ore sintering is a type of powder metallurgy used to pre-treat iron before using it in manufacturing applications. Sintering involves heating iron powder to partially, but not completely, melt the iron particles. The exact process used and additional elements involved vary, with some methods using gas or electricity in addition to heat.
Sinter plants agglomerate iron ore fines (dust) with other fine materials at high temperature, to create a product that can be used in a blast furnace. The final product, a sinter, is a small, irregular nodule of iron mixed with small amounts of other minerals.
Sep 30, 2012· In Japan, the proportions of iron ores charged into the BF are, at present, 15% lump ore, 10% pellets, and 75% sintered ore. Thus, pretreated iron ores represent a large majority of the ore used.
CHAPTER-11 FUNDAMENTALS OF IRON ORE SINTERING R. P. Bhagat INTRODUCTION The process of sinter making originated from a need to make use of fines generated in mines and in ore benefiCiation plants.

In the iron and steel manufacturing, sintering is a pre-treatment step to process fine particles of iron ore, together with other constituents, as feed material for a blast furnace. 1 H. Ahn, S. Choi and B. Cho: 'Process simulation of iron ore sintering bed with flue gas recirculation Part 1 – …
2. Experiments. The iron ore used in this study was a high-grade hematite fine ore with chemical composition presented in Table 1.This ore was oven dried at 105°C for 24 hours and after screening, the –1 mm size fraction was chosen for sintering experiments (due to small volume of compact sinter blends using larger fines is not practical).
SINTERING Sintering is a technology for agglomeration of iron ore fines into useful Blast Furnace burden material. This technology was developed for the treatment of the waste fines in the early 20th century. Since then sinter has become the widely accepted and preferred Blast Furnace burden material.
Q. sintering of iron ore 1. INTRODUCTION :- 40 to 50% iron ore becomes under size which may create pollution in the plant of the mine site. For the utilization of the variable ore, it is necessary to agglomerate the fines into the required size for charging in the blast furnace. Agglomeration is the size incensement process of the fines ore.
