Anodes for the Electrowinning of Manganese

Transactions of The Electrochemical Society, 1939
Manganese is a metal of great importance in the manufacture of steel. Domestic ore deposits are unsuitable for thermal reduction, but may be used in electrowinning from sulfate leach solutions. Lead anodes are unsatisfactory in these solutions because they cause a loss of manganese by oxidation to manganese dioxide. Duriron anodes were investigated but

Adsorption Capacity of Organic Compounds Using Activated Carbons in Zinc Electrowinning

Energies, 2019
The influence of adsorbate (D2EPHA and kerosene) on the process of zinc electrowinning from sulfuric acid electrolytes was analyzed. The main objective was to critically compare three factors: (1) Three types of activated carbon (AC); (2) adsorption ...

Germanium recovery from zinc calcines using a hydrometallurgical procedure

Revista de Metalurgia
In the final stage of zinc calcines processing, zinc is recovered by zinc electrowinning. However, the presence of germanium in the electrolyte seriously affects the current density in the electrowinning step. Since germanium is a critical and strategic

Actinides chlorides electrowinning

, 2015
In the frame of the European SACSESS program (Safety of ACtinides SEparationproceSSes), electrowinning of actinides chlorides was studied in LiCl-KCl (450°C) ontoaluminium and tungsten cathodes in order to evaluate a salt cleaning process for spentelectrorefining salts.
