Extraction of manganese oxide ore by a reduction,

A process for recovering manganese from low-grade manganese oxide ore through a reduction acidolysis-selective leaching method is investigated. Two types of biomass, sawdust and straw, were used as reductants. Reduction acidolysis, using concentrated sulfuric acid, was used to disrupt the structure of the biomass, allowing the biomass to be hydrolyzed into monosaccharides. Analysis by X-ray diffraction revealed that Mn2O3 was reduced to MnSO4. Then, in the selective leachingExtraction and separation of manganese and iron from,,15/01/2019· With the depletion of high grade manganese ore resources, the Fe-Mn ores are becoming important substitution resources for extracting manganese. In general, the production of Mn alloy from manganese ores requires that the Mn grade is more than 30% and the Mn/Fe mass ratio is greater than 5.

Manganese produced by this method are free from impurities. So, it can be used for special steel, coinage alloys, manganese brass and manganese bronze. The electrolyte used for extraction is combination of manganese sulphate, ammonium sulphate and sulphur dioxide. The manganese ore is crushed and cleaned. The crushed ore is reduced to manganese oxide. The reduction of ore is carried out by producing producer gas and oreManganese processing | Britannica,To obtain a product of low carbon and silicon content, manganese ore, lime flux, and coal are fused in a furnace, forming a melt rich in MnO. This is then contacted with silicomanganese or low-carbon silicomanganese. The silicon in these alloys reduces the MnO to manganese metal and is itself oxidized into the slag. The carbon content of the particular silicomanganese reducing agent carries over to the final ferromanganese product—about 1 percent when silicomanganese
