Development of waste utilization technology of manganese mining and beneficiation production

• April 20, 2023

On April 13, 2013, a session of the Department of Chemistry and Chemical Technologies was held at the National Academy of Sciences of Georgia, where Tina Lezhava, PhD, Deputy Director of the R. Agladze Institute of Inorganic Chemistry and Electrochemistry delivered a report – “Development of waste utilization technology for manganese mining and processing production”. Within the framework of project АР-18-281 of Shota Rustaveli National Science Foundation of Georgia, two variants of manganese mining and beneficiation waste utilization technology have been developed. Both options are based on the electroreduction leaching of manganese in the oxidized form in waste (tails, sludge) in the sulfur zone using the Fe3+/Fe2 redox system as an intermediary. With the developed technologies, it is possible to completely process man-made waste containing manganese into products that are in demand on the consumer market, while minimizing the harmful effects on the environment.
