Hint:
this pattern has been obtained from a potash felsdpar
and also can we assign any of these these peaks to Iron Oxide bonds?
Ok, let's start at the left. Actually the first two circles are the same band, which is not a band but a dip due to H-O-stretching vibrations (which means there is less water in your KBr pellet than in the one you used as a reference). In the third circle the two H-C- stretching vibrations of the CH2-moeity can be seen. In case of the forth circle I would guess that this is some spurious CO2 and within the fifth cyrcle you see again a dip, again caused by water (this is the H-O-H bending vibration).
Hi Hamid,...... In my suggestion, specify the condition you run FTIR analysis and also your preparation steps (including the calcinating or sintering temperature). It will help to analyze your sample ( even the XRD data analysis).

Attached my thoughts and also some FTIR spectra for iron oxides from the FDM library . It is possible that the natural iron oxide minerals to have a different spectra so maybe it will be good to try some geochemical investigation for the sample
