Kaolin mining and beneficiation: The role of iron -

2010-3-1  Mössbauer spectra of raw kaolins generally comprise components from iron bound in the structures of kaolinite minerals and iron in ancillary minerals. Of the latter, iron oxides are among the most detrimental to industrial uses. Although a distinction of structural and oxidic iron is generally possible if the oxides are magnetically ordered, Mössbauer spectra of kaolins are generally ...
