Lead Anodes Used for Zinc Electrowinning

Zinc is one of the oldest metals and has been an important material in development of civilization. Today, world consumption of zinc is nearly 10 million tons per annum and is growing at 2-3% per annum. This book contains two main chapters. Chapter one includes; An introduction to Zn electrowinning , Extraction of zinc from ores, Applications of Zinc and its alloys, Optimum electrowinning conditions, Organic additives. In chapter two the authors focused on Literature review. This chapter includes; Lead alloy anodes during electrowinning, Alloying elements in lead alloy, Performances of Pb-Ag anodes during polarization, Oxygen overpotential of lead alloys, Effect of Ag additives on the performance of lead alloy, Current efficiency of Pb-Ag alloys, Potential decay of lead alloy anodes after electrowinning, Experimental determination of the factors affecting zinc electrowinning efficiency and System description of electrochemical noise.
