Influence of sodium silicate on manganese

Influence Of Sodium Silicate On Manganese

manganese sulfate is commonly obtained from leaching solution of manganese ores. the rapid development of manganese industry has led to the decrease of manganese ore grade markedly. the conventional techniques used for ore beneficiation contain gravity separation, magnetic separation, froth flotation, pyrometallurgy and hydrometallurgy.

Development of Pb-MnO₂ composite anodes for electrowinning

Development Of Pb-MnO₂ Composite Anodes For Electrowinning

manganese ions, which typically exist in the zinc electrowinning electrolyte, can influence the anode performance, depending on their concentration and the anode material. the main aim of this work was to develop a new composite anode using mno₂ particles in a pb matrix to improve the anode performance in the zinc electrowinning operating conditions in mn-free and mn-containing electrolytes.
