International Journal of Electrochemical Science, 2017 The alkaline zinc electrowinning process can directly recover powdery Zn metal from oxidized zinc ores and industrial wastes. However, the industrial-scale practice shows that the Zn powders produced generally have a broad particle size distribution, and

Integration of physical operations in the hydrometallurgical processing of spent Zn-MnO2 batteries [PDF]
, 2009 The recycling of spent Zn-MnO2 batteries by hydrometallurgy involves the leaching of material previously treated by physical processing to allow the liberation of electrode particles and the separation of unwanted scrap. The integration of these physical
