Development of a technology for obtaining manganese from waste

In this work, the optimal conditions for the extraction of manganese from manganese-containing slags by sulfuric acid leaching were studied. Studies have shown that adding iron powder and iron sulfate to the reaction mixture increases manganese extraction from 45 % to 52 %, making the process more efficient. The influence of temperature, sulfuric acid concentration, and other factors on the melting process was analyzed. The proposed methods for processing metallurgical waste can serve to reduce the environmental load and increase the economic value of slags due to the extraction of manganese. The results of the research can be used in the metallurgical industry and fertilizer production. This is especially true for regions with limited manganese ore reserves, such as Uzbekistan.
