In Uzbekistan, a significant portion of manganese ores is of low and medium composition and is distributed across the Dautash, Kyzylbayrak, Takhtakarachin, Alisai, and Karatau regions. Existing geological data indicate that Dautash and Kyzylbayrak are volcanogenic-sedimentary, while Alisai belongs to the exfiltration type, with 8–35% manganese in the ores and 5–43% MnO2 in Alisai. This article analyzes sulfuric acid hydrometallurgical schemes for extracting manganese from this raw material, recommending a reducing smelting scheme for oxide ores and a phased smelting-purification-deposition scheme for mixed oxide-carbonate ores. Based on similar scientific research, a comparison was made between the Fe (0), biomass-based reducing agents, and the FeS2 and HNO3–glucose systems; the scheme for obtaining products in the form of H2SO4 + reducing solution + solution purification + MnCO3 or MnSO4 was selected as the most industrial and acceptable from a reagent-logistics perspective. Due to the lack of local field test and pilot results in the uploaded file, some indicators were assessed as inaccurate data, while the economic block was covered as a sensitivity analysis based on the no specific constraint condition.
