What is Electrometallurgy used for?
‘Electrometallurgy’ is the group of technologies used for extraction of metals from solutions, including molten salt solutions (‘electrowinning’), or for the purification of metals by electrochemical dissolution into/deposition out of such solutions (‘electrorefining’).
What does Electrometallurgy mean in chemistry?
Definition of electrometallurgy : a branch of metallurgy that deals with the application of electric current either for electrolytic deposition or as a source of heat.
What is Electrometallurgy of aluminium?
Electrometallurgy is a process that takes place in the form of an electrolytic cell. In the electrometallurgy of aluminium, a fused mixture of alumina, cryolite and fluorspar is electrolyzed. In electrolysis, aluminium is released at the cathode, while carbon monoxide and carbon dioxide are evolved at the anode.
What is the principle of Electrometallurgy?
Electrochemical process of metallurgy The eletrochemical principles of metallurgy are effective in the reduction of metal ions to their respective metals in their solution (or) molten states. The reduction is carried out through electrolysis (or) using reducing elements.
Which metal can be extracted from Electrometallurgy?
Sodium, aluminum, and magnesium are typical examples. Electrometallurgy is a common extraction process for the more reactive metals, e.g., for aluminum and metals above it in the electrochemical series. It is one method of extracting copper and in the purification of copper.
Does anode diminish in Electrometallurgy?
The two applications of electrolysis in which the anode diminishes in mass are; Electroplating is the process in with the coating of one takes place on the other element by the process of electrolysis. For example; the coating of iron with copper.
Which metals are extracted by Electrometallurgy?
Which metals are extracted by electrometallurgy?
What is electrometallurgy Shaalaa com?
Electrometallurgy: A process of extraction of metals by electrolytic reduction of molten (fused) metallic compounds is called electrometallurgy.
What is electrorefining process?
Electrorefining is a process in which materials, usually metals, are purified by means of an electrolytic cell. The anode is the impure metal and the cathode is a very pure sample of the metal (http://www.sparknotes.com/chemistry/electrochemistry/intro/terms/term_B.3.html).
Why is electrowinning necessary?
While electrowinning is mostly used to recover non-ferrous metals such as copper, nickel, tin, cadmium, or precious metals like gold, silver, and platinum, it also has a usage in industries that require wastewater treatment.
