A study of the mechanochemical activation of molybdenum ore concentrate (MoS2) with sodium peroxide (Na2O2) shows that sodium molybdate dihydrate (Na2MoO4 center dot 2H(2)O) is the final crystalline product. The mechanochemical formation of sodium molybdate dihydrate is evidenced by XRD, Na-23 MAS NMR and the increasing solubility of the molybdenum in water as the oxidative reaction proceeds.
