of particulate materials. A dry magnetic separation by a drum type magnetic separator served as a case study to visualize effects of processing of a skarn ore with a high content of cassiterite as ore mineral (~4 wt%). For this material, iron oxides and silicates are the main gangue mineral groups.
Purification of ilmenite from chromite impurities by a two step magnetic separation wherein magnetically susceptible chromite is magnetically removed, followed by an oxidizing roasting of the ilmenite and a subsequent magnetic separation of ilmenite from the remaining chromite impurities to obtain an ilmenite with 1% or less chromite.
This is a type of gravity separation. Magnetic Separation: This involves the use of magnetic properties of either the ore or the gangue to separate them. The ore is first ground to fine pieces and then passed on a conveyor belt passing over a magnetic roller. The magnetic ore remains on the belt and the gangue falls off the belt. Froth Flotation Method: This method is mainly used to remove gangue from sulfide ores. .
· 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 ...

But, there are two classifiions of magnetic particles, strongly magnetic particles, such as iron and magnetite, and weakly magnetic particles, such as rutile, Magnetic separation is generally a low cost method of . iron ore magnetic ...
Magnetic separation methods are used to take the advantage of the difference in the magnetic properties for separating iron ore from the non magnetic associated gangue materials. Magnetic separation can be conducted either in a dry or in a wet environment, although .
Once the exploration of an ore body is successful, exploitation begins. .. material or waste from the benefaction process, which are known as tailings, . Once ferric iron is produced by oxidation of ferrous iron, oxidation which may be ... and Mn. These cations participate in the formation of secondary solids, including simple .
Electromagnetic Separation This method of concentration is employed when either the ore or the lmpurities associated with it are magnetic in nature., chromite, FeCr 2 O 4, containing magnetic SiliCIOUS gangue and wolframite FeWO 4, Containing cassiterite, 8nO 4 (nonmagnetic impurities) can be separated by this method. Electrostatic Separation
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.
In this research, the efficiency of magnetic separation methods for processing of a lowgrade iron pigments ore (red ochre) has been studied. Based on the mineralogical analyses (XRD), thin section and polish studies, the reserve is an iron sedimentary deposit with an average Fe grade of %

Froth Floatation method This method is mainly employed for the concentration of sulphide ores. The method is based on the different wetting characteristics of the gangue and the sulphide ore with water and oil. The gangue preferrentially wetted by water and the ore by oil. The crushed ore along with water is taken in a floatation cell.
