Sep 08, 2020 Gravity separation process and strong magnetic separation process are mainly used to separate coarse-grained (2mm-20mm) and medium-grained weakly magnetic iron ore. Among them, coarse and extremely coarse (greater than 20mm) ores are commonly used in heavy medium or jigging gravity separation technology ;
Jan 01, 2015 Magnetic separation is the only effective way of separating the valuable components of iron ore from the diamagnetic inclusions so far as the extractable iron compounds have a high magnetic susceptibility (as a rule, 20– 90·10-7 m3/kg8).
Jan 01, 2015 Because the crystal water in limonitic ores will report to the iron ore concentrate in magnetic separation, the iron ore concentrate grade is limited to about 52% Fe. Figure 9.17 shows an example of a flow sheet to upgrade a limonitic ore. The ore is mainly composed of limonite and quartz with a grade of about 40% Fe.
Oct 04, 2018 Magnetic Separation and Iron Ore Beneficiation. Magnetic separation is an old technique for the concentration of iron ores and for the removal of tramp iron. Since 1849, a number of patents on magnetic separation have been issued in USA, and texts of some of the patents before 1910 describe a variety of magnetic separators for mineral processing.
magnetic separation. Dry Magnetic Separation of Iron Ore: There are many inherent advantages in processes that utilize dry magnetic separation to beneficiate iron ore. Wet concentration of magnetite ore, in comparison, re- quires 500 to 1000 gal of water per ton of concen- trate produced. This means extensive use of water
However, since most of the weak magnetic iron ore concentrates with strong magnetic separation are not high in grade, and the unit processing capacity of the gravity separation process is relatively low, the combined process of strong magnetic separation and gravity separation is often used, that is, the strong magnetic separation process is

The Need for Magnetic Separation Source: EdisonTechCenter. In India the demand for quality steel has been estimated to be between 56 Mt to 200 Mt in the next decade and, currently, known reserves were estimated to be able to supply steel plants with only 13 Bt to 14 Bt of iron ore concentrate in the next 35 to 40 years (Das et al., 2010).
Magnetic separation is also used in situations where pollution needs to be controlled, in chemical processing, as well as during the benefaction of nonferrous low-grade ores. Magnetic separation is also used in the following industries: dairy, grain and milling, plastics, food, chemical, oils, textile, and more. Magnetic cell separation
Dry processing of iron ore presents an opportunity to eliminate costs and wet tailings generation associated with flotation and wet magnetic separation circuits. STET has evaluated several iron ore tailings and run of mine ore samples at bench scale (pre-feasibility scale). Significant movement of iron and silicates was observed, with examples

1. Magnetite ore stage grinding-magnetic separation process The stage grinding-magnetic separation process mainly utilizes the characteristics of magnetite that can be enriched under coarse grinding conditions, and at the same time, it can discharge the characteristics of single gangue, reducing the amount of grinding in the next stage.
