Our ferromagnetic wet drum separators can be used in iron ore separation plants in both rougher or cleaner beneficiation applications. We also provide demagnetising solutions that reverse the residual effects that magnetic separation has on the magnetic viscosity of ferrous slurries, to return the mineral stream to an acceptable viscosity for downstream processing.

2020-6-23 Magnetic flocculation is a separation method based on magnetic particles. By adding magnetic seeds, non-magnetic flocs become magnetized, and then under an external magnetic field, the sedimentation and separation of magnetized flocs can be accelerated to remove pollutants more effectively (Qiu et al. 2017). It means that, compared with traditional flocculation using only flocculants, the sedimentation rate of magnetic

To effectively reutilize Fe in IOTs, we propose a comprehensive utilization scheme: (1) most Fe in IOTs is extracted by concentrated hydrochloric acid to form FeCl 3 flocculants; (2) after separation from the FeCl 3 flocculants, a small amount of Fe is absorbed on the residue solids, which is further washed out to synthesize micron Fe 3 O 4 as magnetic seeds.

2014-1-10 Sintering followed by magnetic separation has been considered as one of the possible ways of processing brown iron ore phosphorous concentrates. Experiments have demonstrated that on sinter roasting of the concentrate over the entire range of the studied parameters (basicity from 0 to 2 and coke consumption from 3 to 10%) there occurs the transfer of phosphorus from ore constituents into slag

Ore material from the COS is reclaimed by conveyor into a parallel train of two High-Pressure Grinding Rolls (HPGR’s), which grind the ore to a size of 4 mm or smaller. This ore material from the HPGRs is pumped in a slurry to a stage one magnetic separation. A high magnetic field allows separation of non-magnetic material to tailings.

This Magnetite Iron Ore is mined from the Adirondack Mountains in New York State. This is the ore that we use to smelt our bloom iron here at Dark Iron Forge. We try to select the pieces with the greatest magnetic pull. These natural iron ore specimens have such a high concentration of Magnetite that a magnet will stick to its surface.

Yes, adding typically 10 – 20 wt.% MagniF to a polymer or rubber makes it both X-ray and metal detectable. This is called “dual detectability”. You can read more on the special page dedicated to this application on our website or contact one of our team members for extra information.

2017-10-10 Iron ores with lower iron content such as taconite are first processed to concentrate the iron level and drive off volatile impurities. The iron ore is dressed or crushed into 0.5-1 in. chunks, which increases surface area for reactions. Magnetic separation is used to remove some of the undesirable minerals or gangue in the crushed ore.

2021-3-23 ArcelorMittal Prijedor is an iron ore mining company majority-owned by steel and mining company ArcelorMittal. In 1916, Austrian mining companies established the first industrial production of iron ore in Bosnia’s Prijedor area. Those mines were nationalized in the 1950s and were then owned by Iron Mines Luubija.

2011-10-21 Pentlandite (Ni,Fe)9S8 is the principle ore. Pentlandite often occurs along with the iron mineral pyrrhotite and the copper mineral chalcopyrite, and part of the smelting and refining process separates the copper and iron from the nickel. The ore is concentrated by physical means (i.e., flotation and magnetic separation) after crushing.
