us7951282b2 hydrometallurgical processing of 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, either. Conventional MnO2 production requires the pre-reduction ... A process for the improved hydrometallurgical processing of manganese containing materials, the process characterised by the formation of a leach solution or slurry of manganese dioxide containing feedstock and acidic solution, passing a volume of sulphur dioxide gas through the leach solution whereby the levels of dithionate ion generated in the pregnant leach solution are less than about 5g ...

However, since the high-grade deposits have been worked out it has become necessary to concentrate lean ores by more ... The extraction of manganese from a semi-oxidized manganese ore was investigated with sucrose as the reducing agent in dilute sulfuric acid medium. The kinetics of leaching manganese from the complex ore containing MnCO3 and MnO2 was also investigated. The effects of sucrose and sulfuric acid concentrations, leaching temperature and reaction time on the total Mn (TMn), MnO2 and MnCO3

Feb 13, 2021 Manganese was leached from a low-grade manganese ore (LGMO) using banana peel as the reductant in a dilute sulfuric acid medium. The effects of banana peel amount, H 2 SO 4 concentration, reaction temperature, and time on Mn leaching from the complex LGMO were studied. A leaching efficiency of 98% was achieved at a leaching time of 2 h, banana peel amount of 4 g,

A cyclic method for processing manganese ores using sodium sulphate as the basic reagent is described. Sodium sulphate is electrolyzed in a diaphragm cell to give an anolyte-containing sulphuric acid and a catholyte-containing caustic soda, a part of which is carbonated in a cyclic manner to form soda ash. The reduced ore is leached with the anolyte to dissolve the manganese and the impurities ...
