Processed magnetite concentrate is a high-quality energy efficient iron ore product which is needed to feed the Direct Reduced Iron (DRI) process. DRI enables the use of hydrogen as an alternate reductant to fossil fuels, and when fed by renewable energy it makes GREENSTEEL.
The purpose of this research was to determine the effect of CO addition to H2 on the reduction kinetics of magnetite concentrate particles at high temperatures. Experiments were carried out at 1 673 K. The replacement of N2 by CO enhanced the reduction rate considerably. The kinetics of CO reduction is slower than that by …

To expand the application of barium-bearing magnetite in pellets, the oxidation induration mechanism for barium-bearing magnetite concentrate pellets with the BaSO 4 contents from 0 to 8wt pct as an additive was investigated in this paper. The green pellets were preheated at 900 °C for 10min and roasted at 1200 °C for 20min.The XRD, …
In this study, firstly, an ultra-pure magnetite concentrate with 72.12% Fe and 0.09% Si was obtained by reverse flotation from superior magnetite concentrate with 68.38% Fe and 2.33% Si. Then, using the ultra-pure magnetite concentrate as raw material, high-purity reduced iron powder with Fe grade of 99.06% was prepared by …
Through the above process, the magnetite processing plant can obtain more than 65% of high-quality iron ore concentrate, and the recovery rate is as high as 80%. Of course, the specific beneficiation process needs to be determined by the magnetite beneficiation test.
Magnetite concentrate grades range from 65 to 70% Fe with the variation in iron grade largely sympathetic according to the silica content. SiO 2 is <5% from nearly all concentrates, with the majority in the range 2.3–3.5%. Al 2 O 3 is <1.9%, with the majority in the range 0.15–0.51%. Sulfur concentrations vary across the range of deposits ...
Because it was set up to produce magnetite concentrate—a higher grade product which requires an enormous amount of expensive processing and beneficiation. Karara mine, Australia, in 2011 Much of the rhetoric at the time went along these lines: magnetite was the future of iron ore, the first choice of Chinese steel mills looking to …
Magnetite: Magnetite is an iron ore where iron can be found in the form of Fe 3 O 4. Hematite: Hematite is an iron ore where iron can be found in the form of Fe 2 O 3. Presence of Iron. Magnetite: In …
Andrew Forrest gave a big green tick to Fortescue producing a high-grade magnetite at Iron Bridge. ... US475 million profit in 2022 when it shipped 21.4 million tonnes of magnetite concentrate to ...
The Iron Bridge magnetite mine is expected to produce 22 wet million tonnes per annum (wmtpa) of high-grade, magnetite concentrate product. First ore from the mine is planned to be shipped in the first half of 2022. The mine is expected to have a life of more than 20 years with a strip ratio of 0.6 and 30% mass recovery.
Fortescue Metals Group Ltd has successfully made its first magnetite product, remarkably at first run grade of greater than 68% Fe. Further to the successful production of wet concentrate at the Iron Bridge site, it has now been transported through the 135 kilometre specialist slurry pipeline where dewatering and materials handling …
In this study, firstly, an ultra-pure magnetite concentrate with 72.12% Fe and 0.09% Si was obtained by reverse flotation from superior magnetite concentrate with 68.38% Fe and 2.33% Si.
The company has been evaluating the market to find out the interest of the other customers to sell pure magnetite concentrate or blend it with lower-grade iron ore, which contains iron below 59%, to achieve higher margins. Furthermore, FMG is eyeing adjacent magnetite mines to increase the production of high-grade iron ore. Reserves …
The resulting magnetite concentrate contains un-liberated magnetite (magnetite particles that are still attached to other minerals) which requires further milling so that the magnetite can be liberated and extracted.
Discover Magnetite Mines' flagship Razorback Iron Ore Project, poised to produce high-grade and DR-grade iron ore for low-carbon and zero-carbon steel production.

The end result is a high iron grade magnetite concentrate (+65% Fe), with typically very low impurities. The additional processing cost for the production of magnetite concentrate can be offset by the premium price which it attracts from steel mills because of the high iron content compared to benchmark DSO hematite products.
Magnetite is an iron oxide mineral that is generally black and highly magnetic. The latter property aids in the beneficiation of magnetite ores. Magnetite contains 72.4% Fe by molecular weight, which is higher than hematite, but magnetite ores having lower ore grade (generally 20-30% Fe) owing to the presence of impurities.
Titanium magnetite concentrate is a mineral obtained after iron beneficiation of titanium magnetite from the Midi Concentrator in Panzhihua, China. The titanium magnetite concentrate particle size is fine, and the content of minerals with a particle size of less than 0.074 mm reaches about 62%.
Monsen analyzed the oxidation of magnetite concentrate particles with size range between 74 and 100 μm in air flow at the temperature range of 400–800 °C using the same model. The oxidation process follows the parabolic law in these two works. The parabolic rate constant was estimated from the changes in hematite thickness.
