separation of iron from manganese

Separation of manganese from iron in sedimentary processes -

HAZEL (1940) notes a protective action of silica on manganese sols, and PIEBUCCINI (1951) finds that silica precipitates manganese sols only when Ca++ is present. 72 Separation of manganese from iron in sedimentary processes Exploratory experiments in connection with the present work indicated that iron sols are generally more stable than manganese sols, although the difference is not great and is dependent on concentrations and on methods of preparing the sols.

Separation Of Iron From Manganese

The separation of the two metals is only possible when the precipitation of the manganese peroxide is prevented, until the greater portion of the iron has been deposited. This result may be attained by adding sodium phosphate, or, better still, by the addition of ammonium oxalate in great excess. In both cases the characteristic coloration from permanganic acid is developed by the

Extraction and separation of manganese and iron from

During the production of electrolytic manganese or manganese chemical products, the issue of co-leaching of Mn and Fe complicates the purification procedure for the MnSO 4 solution if Fe-Mn ores are used as raw materials. Numerous approaches are reported to realize the selective extraction and separation of Mn and Fe from the Fe-Mn ores.

Separation of manganese from iron in sedimentary processes -

Selective oxidation and precipitation by different species of bacteria can lead to partial separation of the metals, but this is probably not a major factor in the formation of large, nearly pure deposits of manganese or iron compounds. Selective dissolution of the metals from igneous rocks, a mechanism of separation often postulated in the literature, was tested by treating basaltic
