This type of magnetic separation machine is used in wet separation processes for smaller than 1,2 mm of fine grained red mine limonite, manganese ore, ilmenite and some kinds of weakly magnetic minerals like quartz, feldspar, nepheline ore and kaolin in order to remove impurity iron and to purify them.
MAGNETIC SEPARATION PRINCIPLES AND APPLICATION IN BENEFICIATION OF IRON ORES A. Das and S. Roy INTRODUCTION Magnetic Separation is one of the physical concentration processes that utilizes the differences in magnetic properties of various minerals present in the ore body. The

netic separation of iron ore have been in the field of dry processing, where a major revolution in iron ore beneficiation may be taking place. But now consider an area of magnetic separation where dry methods have never lost their attractiveness. Table I.

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.
R.J. Holmes, in Iron Ore, 2015. 9.5.2 Utilization of subeconomic iron ores. As magnetic separators progress toward larger capacity, higher efficiency, and lower operating costs, some subeconomic iron ores have been utilized in recent years. For example, magnetite iron ore containing only about 4% Fe to 15% Fe and oxidized iron ore of only about 10% Fe to 20% Fe are reported to be ...
In the 1860s, magnetic separation started to become commercialized. It was used to separate iron from brass. After the 1880s, ferromagnetic materials started to be magnetically separated. In the 1900s, high intensity magnetic separation was inaugurated which allowed the separation of pragmatic materials.
The idea, which Edison39;s laboratory experimented with during the 1880s and 1890s, was to use magnets to separate iron ore from unusable lower grade ores. This would mean that abandoned mines could be profitable once again through the extraction of iron from sand at the sites. At the time, iron ore prices had risen to unprecedented heights.
