electrolytic recovery of copper from solution

Electrolytic recovery of copper from dilute solutions ...

The electrolytic recovery of copper is one of the methods of preventing the formation of sludges generated by conventional treatments. Electrolysis of metal ions in dilute solutions using vertical electrodes results in low recovery. Therefore, a design consisting of a rotating tubular bed reactor with extended cathode surfaces was developed to improve the mass transfer in the cell. The

Recovery of Copper from Strong Chloride-based Solution

Although the electrolytic recovery of metal from dilute solutions is of considerable importance, there are a number of objections to electro-winning as a means of copper recovery from solution. Its operating, investment and energy costs are rather high. In addition, the acid streams formed at the anodes reduce quality of the products obtained [1]. Cementation is still an

Production of electrolytic copper from dilute solutions ...

The recovery of copper from these solutions has for a long time occurred by precipitating metallic copper while using scrap iron. Being less noble than copper, the iron replaces the latter according to the well known reaction: Fe+Cu 2 + Cu+Fe 2 + This operation, known as cementation, produces a fine copper precipitate requiring a successive refining process by
