Feb 16, 2017 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). The purpose of the sintering process is manufacturing a product with the suitable characteristics (thermal, mechanical, physical and chemical) to be fed to the blast furnace.

A sinter feed with good permeability from ignition until burn-through is required for efficient operation of a sinter plant. In this regard it is necessary to consider the widely held and simplistic view that sinter feeds containing iron ores with high ultra-fines content have low-pre-ignition permeability.
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.
Nov 10, 2020 Granulation and sintering are the two most important steps of the iron ore agglomeration process to produce sintered ore. Since granulation takes place at room temperature and is mainly characterized by physical and interfacial phenomena, while sintering is a thermal densification process involving extensive chemical reactions, the characteristics of the ore blends during these processes …
May 14, 2021 Iron ore is one of Australia's largest export commodities worth around $50-60 billion annually. According to 2017 figures, Australia produces more than 800 million tonnes of iron ore a year, mostly for use in steel production. Research to improve iron ore sintering is helping to maintain one of Australia's major exports.
Iron ore sintering creates substantial off-gas volumes, and treating these in order to meet increasingly stringent environmental standards is expensive. EOS uses recycling technology to reduce off-gas volumes by 40 to 50 %, resulting in smaller secondary gas treatment
1 day ago IRON ORE DAILY: Stricter scrutiny on mills, sintering cuts prompts plunge in seaborne prices Seaborne iron ore prices fell on Monday September 6, due to Chinese authorities taking a stricter stance against steelmakers on steel production curbs and the start of sintering restrictions, sources said.
Sintering of Iron Ores in a Millipot in Comparison with Tablet Testing and Industrial Process . Abstract . To explore the feasibility of small-scale sintering pot testing, a 'millipot' facility (diameter of 53 mm and height of 400 mm) was established and used to examine the sintering performance of iron ores and other non-traditional ferrous ...
Jan 15, 2021 The iron ore sintering process is one of the vital steps -in an integrated steelmaking chain, the goal of which is to agglomerate iron ore fines into porous sinters with a …
Jun 11, 2019 Sintering: A Step Between Mining Iron Ore and Steelmaking By Alison Cestari 06.11.2019 The USGS defines iron ore as a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3).
Low-temperature ( 1300 C) iron ore sinter is an agglomerate of unmelted and partially melted nuclei particles (+ 1 mm) and a matrix bonding phase produced from the melting of fine ore (− 1 mm) and flux particles, with the majority of melt formation occurring in the granule adhering fines layer. The majority of nuclei are hematitic, but they can also be any other unreacted particles such as flux or aluminosilicate …
