ABSTRACT

Regularities of molybdate acid leaching process in sodium carbonate solutions
depending on temperature and concentration of reagents are identified. Also current
intensity influence on electromembrane process parameters and influence of mass
transfer of molybdenum ions on electrolysis of sodium molybdate solutions are
revealed.

Keywords: manganese dioxide, sulphuric-acid leaching, acidity degree, infrared spectroscopy, electromembrane process.
