Extraction of Metals by Molten Salt Electrolysis: Chemical Fundamentals and Design Factors

  • 385 Accesses

  • 7 Citations

Summary

The chemical fundamentals of electrolyte, solute, and cell reactions in molten salt electrowinning and types of electrolysis cells used for this process are discussed. Emphasis is given to the basic physicochemical and electrochemical factors in the optimum design of electrowinning processes. Examples of practical and fundamental limitations encountered in molten salt electrowinning are given. Ways to avoid those limitations are also discussed.
