During the iron ore sintering process, its SiO2 content considerably affects the sinter quality. In this study, the effect of SiO2 content on iron ore sintering indexes was studied, with mineral composition and microstructure analyses. It was shown that the strength and reducibility of sintering products improved when SiO2 content increased. …
After being subjected to geometallurgical evaluation, the iron ores from Singhbhum Bonai-Keonjhar region, eastern India, have been designated as dense martite microplaty hematite high-strength ore (dM-mH-hs ore), massive dense martite microplaty hematite high-strength ore (mdM-mH-hs ore), schistose microplaty hematite low …
The quality of iron ore sinter is a critical factor determining the productivity of blast furnaces for iron-making. CSIRO has therefore been developing capabilities for predicting sinter characteristics, which enables sinter quality to be improved/optimized and preliminary assessments to be made of the suitability of specific ores or ore blends for …

Sintering is an agglomeration process used in the iron and steel making industry. In sinter machine, the fine iron ore particles are agglomerated to form porous coarse particles by combustion of fuel [1,2,3,4,5].After agglomeration process in sinter machine, the hot sinter is crushed by the rotating breaker and transferred to the chute …
Iron ore sintering is an important stage in the production of steel from iron ore. Sinter can constitute more than 60% of ferrous burden in modern blast furnaces in Japan and most blast furnaces in Europe. Iron ore sintering is a high temperature process which converts iron ore fines (<6–8 mm in size, too small for direct feed into the blast ...
Geometallurgy has reached maturity, beyond its early simplistic "geology + metallurgy" conception. ... The results of geological and process data integration are compared with the real case data of an apatite iron ore. The discussed approach allows for studying the implications in downstream processes caused by changes in upstream …
Japan started the national project "COURSE 50" for CO2 reduction in the 2000s. This project aimed to establish novel technologies to reduce CO2 emissions with partially utilization of hydrogen in blast furnace-based ironmaking by 30% by around 2030 and use it for practical applications by 2050. The idea is that instead of coke, hydrogen …
This study combines in situ diffraction experiments in model sinter systems with laboratory-based compact sinter tests using natural ores to examine the links between iron ore …
Some examples of applying geometallurgy for the iron-apatite ore are shown in this paper. The result, the guidelines on planning, executing and evaluating a geometallurgical program, are given in this paper. Evaluation and comparison of different machine-learning methods to integrate sparse process data into a spatial model in …

Each of the seven tools listed in the above table can be used for improving mine performance and after Iron Ore 2017, CSIRO will be conducting a two day workshop: Advanced Characterisation and Geometallurgy of Iron Ores to show how you can …
Vale's operational iron ore pellet capacity is about 41 million tons in Brazil and slightly more than 9 million tons in Oman. Most of its Brazilian capacity is focused on BF-grade pellets while the Oman operation is devoted to DR-grade pellet production, which totaled 9.2 million tons in 2017.
A sample of low-grade iron ore from El Volcan, Mexico, serves as an example to demonstrate in a step-by-step approach how QEMSCAN® analyses provide processing information. ... iron ore samples with different texture but similar mineralogy undergo different degrees of assimilation in compact sintering. • The second example shows that ...
Iron Ore Market Size & Trends "2030 iron ore market value to reach USD 301.86 billion" The global iron ore market size was estimated at USD 289.72 billion in 2023 and is expected to grow at a CAGR of 1.4% from 2024 to 2030. The consumption of iron ore worldwide is anticipated to be driven by the global demand for construction steel.
Geometallurgy is an interdisciplinary approach, which is a rapidly expanding area of ore geology integrating geological, mining, metallurgical, environmental, and economic information of ore ...
The development of DRI plants within the Special Economic Zone at Duqm (SEZAD) is set to transform Oman into a major steel exporter, providing a significant boost to the country's economy. DRI is a high-quality iron ore product that is used to make steel. It is produced by reducing iron ore with natural gas in a process called direct reduction.
Geometallurgy is ideally suited to adopt this approach given that rock textures and ore types are developed at different scales of observation. We might, for example, need to know information at the grain boundary-scale (for liberation or processing behaviour), as well as at the ore deposit–scale (for resource modelling).
Intensification of the iron ore sintering process is approached with a four-way framework covering granulation improvement, waste gas recycling, fuel gas injection into the sinter bed, and reduction of stack emissions. Various metallurgical wastes are granulated to form micro pellets and are dosed along with the feed to cut down the cost.
As part of an initiative to communicate CSIRO's thoughts and future directions within the Iron Ore Geometallurgy space we have instigated a series of informal blogs/conversations. We plan on ...
