01/01/2022 · To upgrade oxidized iron ores, it is therefore important to create magnetic fields with high intensities and high gradients to achieve higher iron recoveries. 1. Jones wet highintensity magnetic separator The Jones wet highintensity magnetic separator was developed in 1956.
Strong collectors, in other words, tend to float small amounts of iron along with the silica. Finely ground (90% less than 325 mesh or finer) magnetic concentrates with iron and silica almost completely liberated are highly responsive to upgrading. Concentrates of the same fine mesh size but containing unliberated ironsilie are less responsive.
