Method for oxidation of pyrite in coal to magnetite and ...

Because pyrite is only slightly magnetic, other separation methods focus on altering the magnetic properties of the pyrite to enhance its magnetic susceptibility prior to magnetic separation. For example, in U.S. Pat. No. 3,961,971 a kaolin clay having improved brightness is prepared by removing a portion of the iron pyrite contaminants ...

2011-1-7  Magnetic separation of minerals is a topic that is seldom reported in the literature for two reasons. First, separation data generally are byproducts of other projects; and second, this study requires a large amount of patience and is unusually tedious. Indeed, we suspect that most minerals probably are never investigated for this property.
