: ADVANCES IN MAGNETIC SEPARATION OF ORES

2016-12-4 plants consistently produced concentrates of more than 71 pct Fe. Edison devoted eight years, at a cost of more than $2 million, to inventing a magnetic process and con- structing a plant for concentrating low grade iron ore into desirable furnace feed. In the 1890's, recog- nizing the iron industry's dependence on the some-

2015-1-1 Different materials possess different magnetic properties by which they may be separated. Figure 9.1a shows that when a magnet is placed close to an iron ball and a ceramic ball, the iron ball will be attracted to the magnet and the ceramic ball will not. Figure 9.1b shows that when a magnet placed close to a group of mixed tiny iron and ceramic balls, most iron balls will be attracted to it ...
