A novel ironmaking technology is under development at the University of Utah. The purpose of this research was to determine comprehensive kinetics of the flash reduction reaction of magnetite concentrate particles by hydrogen. Experiments were carried out in the temperature range of 1423 K to 1673 K (1150 °C to 1400 °C) with the …

The high-pure magnetite concentrate (HPMC) can be obtained from the magnetite concentrate, a kind of bulk commodity as raw material for ironmaking, by simple magnetic separation having the advantages of no pollution and less energy consumption [Citation 20]. Thus, the production of HPMC is cheap and environmentally friendly.

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 hydrogen …

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 …

SVG resumed mining magnetite ore and producing magnetite concentrate at a rate of 2.2 dry metric tons per annum (Mt/a). Later, a debottlenecking initiative helped increase output to 2.8 dry Mt/a, but SVG wanted to investigate options for increasing capacity to 5.6 dry Mt/a. Barr's team conducted a scoping study to evaluate options for ...

Pilot plant metallurgical test work has demonstrated that the production of a magnetite concentrate is achievable using the established benefi ciation techniques of magnetic separation and fl ...

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. This results in higher costs for the production of concentrate for steel smelters.

The use of magnetic gravity separation in the iron ore concentrate production technology combined with fine screening allows removing high-quality concentrate from the process already at the initial beneficiation stages . ... The most contrasting change is observed for the magnetite concentrate from Olkon GOK: the …
