[Title of award-winning research]
Kinetic study of carbonate formation mechanism during manganese treatment in mine wastewater using geochemical model

[Details of award-winning research]
Abandoned mines in Japan still produce wastewater containing high concentrations of heavy metals, and huge costs are incurred for its treatment. In this study, we focused on a mine that produces wastewater with high concentrations of Mn, and clarified the effects of bicarbonate and calcium ions on the Mn removal reaction process in the mine wastewater through reaction kinetics and X-ray microstructural analysis of the precipitates.
