Due to the strong magnetic and easy to grind, one stage grinding is adopted for magnetite with coarse particle distribution, conversely the multi stages grinding. At present the fine grinding technology improves the concentrate grate from 61% to 67%.

iron ore concentrate process - Xinhai

The hematite magnetic separation method is mainly suitable for the beneficiation of hematite ore containing non-metallic minerals. When the slurry enters the separation stage, the magnetic ore particles can be magnetized under the action of an uneven magnetic field, adsorbed on the cylinder and brought to the discharge port; non-magnetic ore particles still exist in the slurry due to the small magnetic field.

iron oxides (magnetite and hematite). The effective separation of these iron oxides is important for the following reasons: Low magnetic separation is usually implemented as a pre-concentration step to reduce the mass streams in the downstream flow sheet [3]; A by-product of high grade iron oxides will increase the feasibility of the planned

Two Factors Affect the Magnetic Separation Process - Xinhai

According to the strength of the magnetic field. Magnetic separation equipment can be divided into weak magnetic field separator (magnetic field intensity is 0.1t-0.2t), medium magnetic field separator (magnetic field intensity is 0.2t-0.5t) and strong magnetic field separator (magnetic …

High Gradient Magnetic Separation of Iron Oxides and …

Goethite, hematite, lepidocrocite, and anatase are concentrated in the magnetic fraction, while quartz is concentrated in the tailings. Chlorite is effectively concentrated in the magnetic fraction. Although mica, vermiculite, and smectite are often found in both the tailings and the magnetic fraction, vermiculite and mica appear to be more concentrated in the magnetic fraction.
