ELECTROWINNING Meaning and
Definition
-
Electrowinning is a process used in metal extraction and purification, particularly in the mining and metallurgy industries. It refers to the method of winning or extracting a desired metal, usually from ore or solutions, by passing an electric current through a solution containing metal ions. This electrical current leads to a reduction of the metal ions, causing them to deposit and form a pure metal on an electrode.
In electrowinning, an electrolytic cell is typically used, consisting of two electrodes: an anode and a cathode. The anode is composed of an inert material, such as graphite or platinum, while the cathode is usually a metal plate or wire that facilitates the deposition of the desired metal. The electrolyte, containing the metal ions, acts as a conductor through which the electric current flows.
During the process, metal ions in the electrolyte are attracted to the cathode due to the electric current and undergo reduction, resulting in the formation of a metallic layer. This layer is then periodically scraped or peeled off to obtain the pure metal product.
Electrowinning is commonly employed in the extraction of various metals, including but not limited to copper, zinc, nickel, and gold. It is an efficient and environmentally friendly method, as it eliminates the need for traditional smelting processes that often release harmful gases and generate significant amounts of waste.
Overall, electrowinning plays a crucial role in the production of high-purity metals and is instrumental in the development of sustainable metal extraction techniques.

Etymology of ELECTROWINNING
The word "electrowinning" is derived from the combination of two terms: "electro" and "winning".
1. Electro: The prefix "electro" comes from the Greek word "ēlektron", which means amber. In ancient Greek, it was observed that when amber was rubbed against certain materials, it acquired the ability to attract small objects. This property of static electricity was characterized by the Greeks, and the name "ēlektron" was given to it. Over time, the term "electro" has come to represent anything related to electricity or electrical phenomena.
2. Winning: The term "winning" in this context is used in the archaic sense, derived from the Old English "winnan". It means "to work, to strive", or "to gain or achieve".
