Following solubility tables http://en.wikipedia.org/wiki/Solubility_table :
1°)(NH4)2SO4 solubility is less in water than NH4NO3
2°) Solubility of (NH4)2SO4 increases slighly with temperature; while the solubility of NH4NO3 increases a lot with temperature.
So it seems as simple as heating a maximum amount of the salt in the minimum amount of boiling water (100°C or more)...decanting the non dissolved
salt...the warm liquid upper layer will deposit upon cooling to 0°C a good deal of NH4NO3 cristals and a little (NH4)2SO4.
