1. Introduction. Manganese is a strategically important metal in industry and human life. It is widely used for production of steel, non-ferrous alloys, dietary additives, fertilizers, dry cell batteries, paints and other chemicals [1], [2], [3].With the rapid growing demand for manganese, rich manganese ores are being overexploited, leading to a …
For the calcification roasting process with n(CaO)/n(V 2 O 3) of 2, the leaching rate of manganese decreases gradually with the increase of m(MnO)/m(V 2 O 3), which shows that manganese plays the smaller role in the process of vanadium extraction due to the introduction of calcium salt. Furthermore, once the amount of calcium salt …
Through counter-current extraction and reverse extraction, the manganese ion extraction rate was 97.23% and the concentration of impurity magnesium ions in the electrolyte was reduced from 5.03 g·L −1 to 0.56 g·L −1, resulting in an increase in the theoretical number of electrolyte cycles from 5 to 45. In addition, the enriched impurity ...
