A bit difficult to answer. It depends on many factors i.e. the content of the oxides, their mineralogical composition. If iron oxide presents as magnetite then try to use magnetic separator. About calcium, as said above it depends on the how much calcium oxide in your mixture. Very likely you have to use a chemical acid treatment if the content is low.

Yu-Chen Lee

Your question is not specified. It's difficult to answer it. Besides, CaO is not worthy to recovery when compared with other oxides.

Vladimir Kozlov

I suppose that Fe oxide may be separated by using a magnetic field.
