Jan 02, 2012· For example, the magnetite ore at LKAB (Luossavaara-Kiirunavaara AB) in Kiruna, Sweden, contains about 1 wt% phosphorus, which is removed by magnetic separation in combination with flotation[43-44]. In hematite and goethite ores, phosphorous tends to be dispersed and incorporated into the lattice of iron minerals.
Iron Ore Beneficiation Process 911 Metallurgist. Apr 27, 2017 The general processes to which low grade iron ores are amenable are as follows: and Table Concentration are in use, and a plant for a fifth process, magnetic concentration, Brunt, the gear drives, etc., being too light in design to stand up under the severe work.
Lower-grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, high-quality fine ore powders, are known as fines. Magnetite. Magnetite is magnetic, and hence easily separated from the gangue minerals and ...
Karara comprises a large-scale, long-life magnetite orebody amenable to bulk mining and processing. Magnetite ore has lower iron content (34-36% Fe) than hematite ore (58-64% Fe). It must be upgraded by a complex ore treatment process (beneficiation) to produce a high-grade (+65% Fe) concentrate …

In order to obtain high-grade concentrate, magnetite concentrate can be treated by reverse flotation or high-frequency fine screen. In addition, in order to improve the recovery rate, the tailings reprocessing process can be considered to further recover the magnetic minerals. 2. Polymetallic magnetite separation process
