Magnetic separation and evaluation of magnetization of

May 01, 2000 When discussing the magnetization of the different soil fractions, it can be seen that the sand fraction all the Fe-rich soils derived from mafic rocks and itabirites have high magnetization values varying from 2 to 17.7 J T −1 kg −1, with no exceptions. These values demonstrate that all of these soils have ferrimagnetic minerals in their ...
