摘要：

This paper pertains to the kinetics of dissolution of molybdenum from secondary sources containing metallic molybdenum. According to the literature, molybdenum can be dissolved in oxidizing acidic media such as nitric acid (HNO3) and hydrogen peroxide (H2O2). Therefore, two nitric acid containing media, HNO3-HCl (aqua regia) and HNO3-H2SO4 and one H2O2 medium were investigated for this purpose. Reaction in all solvents, i.e., HNO3-HCl, HNO3-H2SO4 and H2O2, was of double decomposition type with first order rate kinetics. Although dissolution of only a few molybdenum sources was studied, results can be applied to all type of molybdenum metal secondary source types.
