How Hydrometallurgy and the SX/EW Process Made Copper the

IntroductionConventional Copper ExtractionThe SX/EW ProcessBacterial LeachingConclusionContacts and ReferencesAlso in This IssueCopper is traditionally known as the \"red\" metal after its natural color. However, it is also known as a \"green\" metal for the green patina that it acquires due to weathering. Indeed, patinized copper is the architectural focal point of many modern buildings for its natural look. Beyond this, however, copper can truly be cited as the \"green\" metal both for its role in protecting the natural environment through its use in energy-saving applications and for the achievements that have been reali

Pyrometallurgy - an overview ScienceDirect Topics

The nickelcopper-dominated sulfide concentrate is recovered through the extractive pyrometallurgical-process route by conventional roasting and reduction processes that yield a metal of greater than 75% nickel purity. Nickel with high purity can be used directly without further purification, depending on the composition of the impurities.

Copper Mining and Processing: Processing of Copper Ores

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different

Hydrometallurgy - Wikipedia

Hydrometallurgy is a method for obtaining metals from their ores. It is a technique within the field of extractive metallurgy involving the use of aqueous chemistry for the recovery of metals from ores, concentrates, and recycled or residual materials. Metal chemical processing techniques that complement hydrometallurgy are pyrometallurgy, vapour metallurgy and molten salt electrometallurgy.
