9783659804779: An Introduction to Copper Electrowinning
The electrowinning of copper ions derived from leaching, or solvent extraction is a significant contributor to the global copper commodity supply. The process of electrolysis for copper was first developed in the late 19th century and despite numerous advancements in technology the principles and basic equipment remain the same.
High Power Rectifiers for the Electrowinning Industry The
extraction and refining of copper, zinc and other nonferrous metals. That is why ABB offers an integrated system of DC power supplies for electrowinning processes that provide an unrivalled low life cycle cost to give you technical performance that boosts productivity and allows a high return on investment on your plant.
In contrast to electrowinning, which faces com petition from other primary extraction processes, electrorefining is virtually unrivalled in its capability to produce metal of the highest purity. Copper is the predominant metal to be electrorefined, as this is the only process for preparing metal pure enough for electrical appliions.

SX EW Capital & Operating Cost of Solvent Extraction
Solution mining followed by solvent extractionelectrowinning (SXEW) is one possible way to economically extract copper from ore bodies which cannot otherwise be profitably exploited. Published costs for the unit processes of SX and EW are out of date especially in view of the newer reagents now available and the newer circuit configurations.
Electrowinning Copper Key Concepts. Electrowinning refers to the process of using electrolysis to extract a metallic element from the compounds in its ore. Copper occurs on Earth both as native copper (the uncombined element, Cu), and in ores (copper compounds, or mixtures of compounds, from which copper metal can be extracted profitably).

Firerefined copper is adequate for noncritical appliions such as water tubing, bar stock, or ingots for alloying. Copper intended for electrical uses, however, is produced by electrorefining or sometimes electrowinning techniques. Electrorefining process Virtually all copper produced from ore receives an electrolytic treatment at some stage

Electroplating is a process that uses an electric current to reduce dissolved metal ions so that they form a thin coherent metal coating on an electrode. The term is also used for electrical oxidation of anions on to a solid substrate, as in the formation of silver chloride on silver wire to make silver/silverchloride electrodes.
duction of hode copper. Assuming an ore grade of 0.55 percent and a recovery rate of87.5 6.4 percent copper in the concentrate, concentrating 1 ton of copper ore requires over 200 billion Btu, or approximately 42 million Btu/ton of hode copper.10 Grinding accountsfor roughly 6 0 percent of the total energy consumed in proc
