ELECTROLYSIS AND THE PRODUCTION OF METALS
This chapter focuses on the process of electrolysis and the production of metals. When chemical changes accompany the conduction of electricity through solutions or fused salts, the process is called electrolysis and the substances that have been involved; either fused or in solution, is called electrolytes.

23.10: Electrolysis of Molten Salts and Electrolysis of Brine
Electrolysis of Aqueous Sodium Chloride. It may be logical to assume that the electrolysis of aqueous sodium chloride, called brine, would yield the same result through the same reactions as the process in molten (ce{NaCl}). However, the reduction reaction that occurs at the cathode does not produce sodium metal, instead, the water is reduced.
Extraction of Metals | CIE IGCSE Chemistry Revision Notes …
More reactive metals are extracted by electrolysis. The electrolytic extraction of metals consumes large amounts of electricity so this is reflected in the cost of the metal. Extraction of iron from hematite. The extraction of iron metal from iron ore uses a blast furnace, a huge tower used to extract iron from its ore, hematite.
Electrolysis: Definition, Process, Equations, Examples, and …
The metal part gets deposited as a solid metal. The nonmetal part is released as gas. The electrolysis of aqueous ionic compounds is complicated. Water produces hydrogen ions (H +) and hydroxide ions (OH –) and competes with the primary compound. Hence, hydrogen (H 2) and oxygen (O 2) gasses can also liberate [5]. Examples of Electrolysis [1 ...
Electrodialysis for metal removal and recovery: A review
Electrodialysis (ED) is a multipurpose technology that can be used for treating acidic effluents containing metal species. Its continuous operation capacity, scalability, and easy operation can solve most of the drawbacks of current technologies, and the direct reuse of concentrated metal streams can avoid the need for chemical …
