The ore was concentrated in ore belts and usually mixed with other types of rocks, often granite and limestone. Magnetite is magnetic Edison took advantage of this unusual mineral property in the design of his Magnetic Ore Separator. Figure 3. Iron ore from the Edison Mines. Iron ore has been mined at this site since the late 1700s.
Oct 25, 2006 Magnetic separation. The increasing use of magnetic solid carriers in biochemical and molecular biology processes has many advantages compared to other non-magnetic separation processes. The term magnetic means that the support obtains a magnetic moment when placed in a magnetic field. Thus, it can be displaced.
Oct 20, 1979 The ore was transferred to a magnetic separator that Edison invented. ... But the magnetic separator is still being used in a modified form

samples are investigated. The Davis tube magnetic separator is an efficient tool to use in rejecting the non-magnetic mineral particles from an ore sample. The middlings discarded by the tube separator usu- ally are so low in iron content that they can be con- sidered relatively unimportant in liberation studies.

To enhance effective use of resources, we use magnetic separation method on the experiment study of a refractory oolitic hematite ore. Research showed that the grade of raw ore (TFe) was 47.44%, and magnetic iron grade (MFe) was 28.59%. Through magnetic separation experiment, threestep magnetic separation process was chosen.
Jan 14, 2013 His ore separator did not work well. He pulled out of the venture in 1894 in the midst of an economic depression. In 1915, PRCIC sold the 1,000-acre property to Clarence Fahnestock, whose brother later donated the land to the Taconic State Park Commission, helping to create the state park that today bears the Fahnestock name.

The idea, which Edisons 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.
The present invention refers to a system and method for the totally dry treatment of iron-ore wastes from previous mining operations, suitable for both the processing of ore wastes deposited in barrages and wastes stored in piles.
