    Copper extraction - Wikipedia

    Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.

    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

    Copper Recovery by Solvent Extraction Techniques

    Since it is common for the copper solvent extraction plant to supply feed electrolyte to an electrowinning plant, it is useful to combine the operating costs for the two plants when comparing costs of copper recovery by solvent extraction techniques with those for cementation.
