氧化锰矿浆脱除电解锰渣煅烧烟气二氧化硫工艺研究-四川大学
The desulfurization rate increased with the decrease of the granule size of manganese oxide and the size of the manganese ore used for desulphurization should be less than 120 mesh. The operating temperature of flue gas desulfurization should be controlled in the range of 50 ℃ ~ 80 ℃, while the liquid-solid ratio should be in the range The leaching of manganese carbonate ore was a rapid process, with the majority of Mn leached within 15 min. At the 30-minute mark, the leaching of Mn tended to be stable, and further extension of the leaching time had negligible impact on the leaching efficiency of Mn.

Removal and Resource Utilization of High Concentration
The removal of high concentration flue gas sulfur dioxide (SO2) using manganese carbonate ore desulfurization (MCO-FGD) is a promising route that combines economic benefits and pollution control. However, the problems of intermediate oxidation and by-product control have plagued the industrial application of the MCO-FGD TECHNICAL PAPER Preparation of Industrial Manganese Compound from a Low-Grade Spessartine Ore by Hydrometallurgical Process Alafara A.

Manganese: The overlooked contaminant in the world
1. Introduction. Manganese (Mn) is a widely distributed element in terrestrial and coastal ecosystems but usually occurs as trace amounts in most organisms (Levy and Nassetta, 2003, Pinsino et al., 2012).It is found in rocks (e.g., Mn content in Basalt: 1300 mg kg −1; Gneiss: 600 mg kg −1; Limestone: 550 mg kg −1; Graham et al., 1988), Selective-reductive leaching of manganese from low-grade manganese ore using tannic acid as a reductant in acidic media was demonstrated by XRD, SEM-EDX characterization, and batch leaching studies at room temperature. The pH change in the liquid phase before and after leaching revealed that selectivity of manganese over iron Selective-Reductive Leaching of Manganese from Low-Grade Manganese Ore

Hydrometallurgical Production of Electrolytic Manganese
The ferromanganese (FeMn) alloy is produced through the smelting-reduction of manganese ores in submerged arc furnaces. This process generates large amounts of furnace dust that is environmentally problematic for storage. Due to its fineness and high volatile content, this furnace dust cannot be recirculated through the process, Froth flotation is the process generally recommended for the beneficiation of low and medium grade ores because of the floatability characteristics of the manganese. The present work has been taken with waste Manganese ore from Garividi mines (Vizianagaram District). Manganese ores of major commercial importance are pyrolusite Beneficiation of Manganese Ore Using Froth Flotation

A sustainable reduction roasting technology to upgrade
Reduction roasting of manganese ores is a known process; however, it is not yet commercialized mainly due to various techno-economic issues. The current research work presents results of a large-scale plant trial performed at a commercial Direct Reduced Iron making plant to upgrade low-grade ferruginous manganese ores (Mn: 25–32%, Manganese ore decomposition is known to be achieved by means of processing the ore with HCl, HBr, H 2SO 4, HNO 3 or their mixtures depending on the mineral form of the manganese, which will interact with certain reagent [8,9].
