High-phosphorus oolitic iron ore, treated by suspended flash magnetic roasting, contained 42.73% iron (mainly present as magnetite) and 0.93% phosphorus (present as collophane). Low-intensity magnetic separation (LIMS) was combined with reverse flotation to increase the iron and reduce the phosphorus contents of the roasted product. The results …
The results show the expediency of stagewise removal of iron ore concentrate to reduce losses with tailings of magnetite particles finer than 10–15 (mu) m, in which the magnetic susceptibility decreases by 1.5 times and more relative to the initial level.
Importantly, magnetite is suitable for processing into iron ore pellets for use in modern steel production and currently accounts for approximately % of global iron ore production. The …
Medium Intensity Magnetic Separator (MIMS) are magnetic drums which are installed in rows of permanent magnets that generate a very high and homogeneous magnetic gradient to attract and concentrate the weakly magnetic iron ore. The MIMS can be used in a current with the material flow or a countercurrent.
Extraction of iron from Sanje ore by single stage magnetic separation or flotation process did not produce high grade iron concentrate with silica and alumina content. This is because Sanje ore has iron mineral particles which are strongly aggregated with silica and alumina and disintegration using single separation technique was difficult.
The annualized plant results demonstrated that an iron ore concentrate containing 68.4% Fe could be produced using this flow sheet from run-of-mine ore containing 29.1% Fe, …
Iron ore concentrate is an output product from processed iron ores that have been milled (crush, grind, magnetic separation, flotation) to separate deleterious elements and produce a high-quality product. Sintering …
The results show that by only adopting traditional magnetization roasting–magnetic separation, an iron ore concentrate containing 57.49% Fe and 1.4% P 2 O 5 at an iron recovery rate of 87.5% and a dephosphorization …
In this study, a pilot-scale experiment on the iron recovery from iron ore tailings was investigated using innovative technology of pre-concentration and suspension magnetization roasting (SMR), followed by magnetic separation and flotation.
The iron ore sample was collected from magnetic separators concentrate stream of Gole Gohar iron ore complex with d80 equal to 90µm. Sulfur and total Fe contents of the sample were found to be 0. ...
The chemical multi-element analysis of raw ore, transformed products, iron concentrate, and tailings is shown in Table 2. Table 2 shows that the TFe content in the raw ore was 48.15 %, and the FeO content was less than 0.01 %. This indicated that iron in the raw ore was not present in FeO, indicating a very low content of highly magnetic magnetite.
