[PDF]ADVANCES IN MAGNETIC SEPARATION OF ORES

M agnetic separation occupies an attractive posi- tion in the field of ore beneficiation. It is a sim- ple yet effective method, used for some 150 years and steadily growing more important. This type of beneficiation orginated in 1792, when William Ful- larton was issued a British patent covering the sep- aration of iron ore by magnetic attraction.
