Maximizing the recovery of fine iron ore using magnetic separation Most iron ore operations that require beneficiation of ROM ore to produce lump fine (sinter) and pelletizing concentrate iron ore products will discard a slimes fraction to final tailings This fraction can vary in particle size from –200 m down to –10 m The general view is that this fraction is low grade in terms

Probably the biggest financial failure of Edison's career was the magnetic ore-separator The idea which Edison's laboratory experimented with during the 1880s and 1890s was to use magnets to separate iron ore from unusable lower-grade ores This would mean that abandoned mines could be profitable once again through the extraction of iron from sand at the sites At the time iron

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 These demagnetising coils generate a magnetic field that alters magnetic orientation at 200 Hz
