USA Electrowinning of copper Google Patents
Copper is processed via solutions of copper salts, both cupric and cuprous, in acidified aqueous solutions containing organic nitriles. Methods of producting solutions of cuprous salts include reduction of cupric salts and oxidation of copper and copper sulphides. Solutions of cuprous salts are thermally or electrochemically disproportionated to produce copper and solutions of cupric salts.
Electrowinning of Nonnoble Metals with ... Harry J. Ploehn
els can aid in the design and operation of porous electrodes in order to maximize the advantage of these highsurfacearea materials. The theory and operation of porous electrodes have been developed to sophisticated levels, including their use in the recovery of relatively noble metals such as copper (see, for example, Ref. 3 and 4).
Copper extraction Wikipedia
Copper extraction refers to the methods used to obtain copper from its 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.
Carbon Stripping – Denver Mineral Engineers
carbon stripping vessel at a flow rate of about 2 Bed Volumes per hour. Gold and silver values are recovered from the pregnant solution by electrowinning and the barren solution is reheated and recycled through the stripping vessel. Glycol consumption is typically in the range of 20 to 40 gallons, per ton of carbon stripped. VI. MICRON STRIPPING

The Reaction of Aluminum to Copper in Electrolysis ...
Electrolysis has many practical and industrial applications. For example, it is used to purify aluminum. In this case, the aluminum is obtained from an ore called bauxite. The electrolytic cell used in this process typically does not involve a copper anode. Instead, the anode is usually made of carbon. Electrolysis is also used in electroplating.
