What's the Copper Electrowinning?

Copper is element number 29 on the Periodic Table of Elements. It is considered a semi-precious, nonferrous, malleable metal with many hundreds of applications in the areas of electricity and electronics, plumbing, building construction and architecture, industry, transportation, and consumer and health products.

Copper cathode

Pure copper's melting point is 1,981°F (1,083°C, 1356°K). Its most important properties include superior heat transfer, electrical conductivity and corrosion resistance. Refined copper cathodes are always gotten through electrowinning process.


Electrowinning, also called electroextraction, is the electrodeposition of metals from their ores that have been put in solution via a process commonly referred to as leaching. Electrorefining uses a similar process to remove impurities from a metal. Both processes use electroplating on a large scale and are important techniques for the economical and straightforward purification of non-ferrous metals. The resulting metals are said to be electrowon.

Except copper, other non-ferrous metals are also gotten through electrowinning, these metals include: 

Copper

Zinc 

Lead 

Gold

Silver

Chromium

Aluminium

Cobalt 

Manganese

Rare-earth 

Alkali metals
