Jul 01, 2021 Alteration of crystalline structure and magnetic property of these minerals enables separation of low-grade ore by using magnetic separation. It is found that low-grade ferruginous chromite ore can be upgraded by reduction roasting, and 61.2 Cr 2 O 3 was recovered with a chromium-to-iron ratio of 1.93 from a feed chromium-to-iron ratio of 1.01.
To fulfil requirements of mettalurgical grade 48 Cr 2 O 3 with CrFe ratio 31 need the right beneficiation, one of them is using magnetic separator. Chromite sand sample obtain from Konowe-Southeast Sulawesi have low grade, so it needs process to enrichment CrFe Ratio. CrFe ratio feed was 0.55, after the process for size variation, roll speed, feeder speed and electric current decline Cr ...
Mar 04, 2015 The CrFe ratio chromium-to-iron mass ratio of chromite affects the production of chrome-based ferroalloys. Although the literature contains numerous reports related to the magnetic separation of different minerals, limited work concerning the application of magnetic separation to fine chromite from the Sukinda region of India to enhance its CrFe ratio has been reported. In the present ...
The magnetic separator has two consecutive separation steps. In the first step, magnetic metal parts are removed, while in the second step, the chromite sand is separated from the quartz sand with a stronger magnet. If necessary, a third step with a magnet with an even stronger magnetic field can be included in order to reclaim almost 100 pure quartz sand. Each magnetic roller has a magnetic disk, whereby
Chromite fines recovery and or upgrading Ilmenite fines recovery Wollastonite upgrading Kyanite recovery Apatite upgrading Sulphide ore recovery and separation The success of any magnetic separation process is governed by the property of the material to be collected and the structure

Vol.8,No.5 Characterisation and Pre-concentration of Chromite 375 Effect of Bed PressureFloatex density separator works based on the principle of hindered settling. Richardson and Zaki proposed the particle slip velocity, which is the relative velocity between the particle and water velocity, is a function of the terminal settling velocity and ...
The chromite is associated with magnesium and as a result, it is expected that separation of chromite by magnetic separation will be easier and will occur at a higher magnetic strength as compared to the ferruginous ores 8. Further studies need to target recovery of these fine chromite using high intensity magnetic separation. Mg Si Al Cr Fe Ca
Minprotech established the first Wet High Intensity Magnetic Separation WHIMS plant for chromite recovery in South Africa. Minprotech is the market leader utilizing WHIMS technology to extract chromite from UG2 and LG reefs. Our first full production plant was built and operated by us for a major chrome producer on the Eastern Chrome Mines.
