The depletion of high-grade iron ore in recent years [] necessitates a technology that can utilize low-grade ultra-fine ores.To achieve this, steelmakers have been studying the sinter–briquette complex firing process [2,3,4].Iron ore sintering is a typical agglomeration process for manufacturing blast furnace ferrous burden.
Iron ore is the primary raw material used to make steel. Steel is strong, long-lasting and cost-efficient – making it perfect for everything from washing machines to cars, bridges and skyscrapers. According to the World Steel Association, steel is the …
Iron ore lump and sinter fines are examples of DSOs, which are mined predominantly from areas such as Australia's Pilbara and Brazil's Carajas regions, where geological processes have led to iron content levels of between 55% and 65%. These ore types require little processing beyond crushing and screening before being 'directly-shipped ...

FUNDAMENTALS OF IRON ORE SINTERING R. P. Bhagat INTRODUCTION ... super-fluxed sinter in order to incorporate the lime required for fluxing the acid ... In sintering, a shallow bed of fine particles is agglomerated by heat exchange and partial fusion of the quiescent mass. Heat is generated by combustion of a solid fuel ad mixed
Mandatory application of the iron ore fines schedule as per the IMSBC Code requirements: applies only to iron ore cargoes containing BOTH: (a) 10% or more of fine particles less than 1 mm (D 10 ≤ 1 mm) ; and (b) 50% or more of particles less than 10 mm ( D 50 ≤ 10 mm). However, if the total goethite content is 35% or more by mass, iron ore fines may be carried in accordance with the ...
The idea of rolling moist fine ore in a drum to form balls and then drying and firing it was first ... Sinter feed 0.15 6.3 Agglomeration by sintering to be fed in blast furnaces Pellet feed <0.15 Agglomeration by pelletizing to be fed to blast furnace and direct reduction Table 1. Iron ore products classification for ironmaking [3].
Theory and Practice of Sintering of Iron ore. 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 ...

Fines are the fine particles of manganese ore created when crushing manganese rocks. The fines are heated to sinter them (make them stick together, or become "agglomerated"). "The mines produce a lot of fines," Hockaday explained. "But they can't sell them, as furnaces won't buy materials that are too fine.".
Finex is an innovative ironmaking process based on the direct use of fine ore and non-coking coal. In the Finex process, fine iron ore is directly charged at the top of a cascade of fluidized-bed reactors, where it is heated and reduced to direct-reduced iron (DRI) by means of a reduction gas derived from the gasification of the coal in the ...
Ultra-fine iron ore 0 10 20 30 Total 100 100 100 100 Test studies were carried out at 35% domestic iron ore and 10 % iron bearing dust in sinter blends formed with a small basicity value of 1.75. The amount of return dust was kept constant at 10%. 4. Effects of Ultra-Fine Iron Ore on Sinter Quality
Iron ore sinter is an ordinarily utilized iron-bearing burden in BF iron-making unit. The sintering agglomeration procedure aims to form high strength sinter including granulating of the mixed materials, distributing the granulated materials and then igniting the fuels (coke or coal), sintering the iron-bearing materials by the combustion of fuel in a grate with air-suction beneath the grate ...
Recently a special attention is paid on the utilization of ultra-fine iron ore (-0.2 mm) in the form of micro-or mini-pellets in the sintering process. In the current study the ultra-fines iron ...
iron ore sinter fine index started at $70/t in January, peaked near $120/t in July, and settled around $80-90/t for most of the second half of the year. Pellet premiums also experi-enced volatility during the year. On the other hand, the price for steel products decreased during …
The effect of replacing fine ore by coarse ore on sintering reactions was investigated using an infrared furnace on laboratory scale and sinter pots on pilot plant scale. Five sinter mixes were prepared by changing the percentage coarse ore from 0% to in 25% increments.
The whole melting curve of iron ore during sintering process was obtained, and the melting characteristics of iron ore were defined and explained. The whole melting process of mixture, mixed by iron ore and CaO reagent at basicity of 2. 0 and 4. 0, respectively, was observed using a SiC heating furnace with camcorder unit, and the melting curves of mixture that were relative height vs ...
Iron Ore Sinter. Iron ore sinter – A bulk material for blast-furnace smelting, which is made by sintering ore, limestone, fine coke, screened sinter and blast-furnace dust on special belt sintering machines. Sinter quality is determined by the Fe content of iron ore, strength, destruction during heating and reduction in a blast furnace.
Sinter is the primary feed material for making iron and steel in a blast furnace. 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, ...
In this study, a number of commercial iron ore concen-trates were tested in a sinter pot to find their sintering char-acteristics in conventional sintering.
