Description

MnO2, MnO2+FeSO4 and Fe2(SO4)3 are used respectively as oxidant for acid leaching of a uranium ore after gravity dressing. The results indicate that Fe2(SO4)3 can obviously reduce the consumption of H2SO4 and accelerate leaching rate with lower temperature. The leachate with Fe2(SO4)3 has lower concentration of P and Mn.
