Probably the biggest financial failure of Edison's career was themagnetic ore-separator. The idea, which Edison's laboratory experimented with during the 1880s and 1890s, was to use magnets to separateiron orefrom unusable lower-grade ores. This would mean that abandoned mines could be profitable once again through the extraction ofiron...

FromKlein and Bricker(1977).Magnetite(Fe 3 O 4) is a common iron ore mineral in iron ore deposits of metasedimentary and magmatic origin. Magnetite has an inverse spinel structure and is partly altered in near-surface environments to hematite or kenomagnetite ( Waychunas, 1991 ).

Ironisn't the only element that displays magnetism.Nickel, cobalt, gadolinium, terbium, and dysprosium are also ferromagnetic. As withiron, themagneticproperties of these elements depends on their crystal structure and whether the metal is below its Curie point. α-iron, cobalt, and nickel are ferromagnetic, while γ-iron, manganese, and chromium are antiferromagnetic.
