Abstract
The residue from the treatment of reduced manganese ore with methanolic cupric chloride solution, in the previous report, includes various oxides of manganese and iron. In this study a fractional method of determination of manganese monoxide in the above residue is investigated. As the result of experiments, the treatment of the residue by adding 20 mL of 6 N ammonium-sulfate solution and heating in a boiling-water bath for approximately 30 min in CO2 stream was decided as a suitable method of dissolving manganese monoxide only with nearly none of the other oxides being brought into the solution. After filtering the solution, the manganese in the combined solution of the filtrate and the washing is determined titrimetrically as manganese monoxide fraction of the residue by means of persulfate ferrous-permanganate method.
