8: Magnetic Ore-separator - 10 Inventions by Thomas

Probably the biggest financial failure of Edison's career was the magnetic ore-separator. The idea, which Edison'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 ...

Magnetic Separation and Iron Ore Beneficiation – IspatGuru

04/10/2018  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 - Wikipedia

Magnetic separation is the process of separating components of mixtures by using magnets to attract magnetic materials. The process that is used for magnetic separation detaches non-magnetic material with those who are magnetic. This technique is useful for not all, but few minerals such as ferromagnetic (materials strongly affected by magnetic fields) and paramagnetic (materials that are less ...

Iron Ore Magnetic Separation

This, I think, was the first use of magnetic iron-ore concentrates in a blast furnace. The small machine was of the belt type. Mr. Ball soon after designed a drum-type machine, and later a double-drum machine in which a three-part separation was made. There are now magnetic machines of many types, but the majority use the alternating pole magnets. Until 1908, I thought I was the first to use ...
