Publisher Summary. This chapter highlights that electrolytic refining is the principal method of mass producing high-purity copper. Copper from electrorefining, after melting and casting, contains less than 20 ppm impurities, plus oxygen which is controlled at 0.018–0.025%. Electrorefining entails electrochemically dissolving copper from ...

The final step in Cu pyrometallurgical processing is casting of flat, thin anodes for electrorefining. The anodes must be strong and smooth surfaced for efficient electrorefining—bubbles or blisters of SO 2 are unacceptable. Blister formation is prevented by removing sulfur and oxygen from molten copper by air oxidation then hydrocarbon ...
· The electrorefining process of the non-commercial Cu anodes was tested on the enlarged laboratory equipment over 72 h. Cu anodes with Ni content of 5 or 10 wt.% and total content of Pb, Sn, and Sb ...
· The 99% pure copper from the anode furnace is cast into 750-pound, 3-inch thick, rectangular slabs called anodes. The final step is a process called electrorefining. This is done by electrolysis where the copper anodes from the …
· The electrode processing after electrorefining is investigated. This process consists of oxidizing the actinides remaining in the liquid electrode by adding CdCl 2 and removing the associated chloride by high-temperature distillation. During the electrorefining of irradiated metallic fuel, the fission products accumulate in the molten salt.

· Electrowinning is a widely used technology in modern metal recovery, mining, refining and waste water treatment applications. Electrowinning is one of the oldest electrolytic processes known and was first introduced in 1807 by English chemist Humphry Davy. After 66 long years the first commercial refinery Balbach and Sons Refining and Smelting ...
In copper processing: Electrorefining. This is the final step in both pyro- and hydrometallurgical processing. In the electrolytic process, copper anodes and starting sheets are immersed in an electrolytic solution made up of copper sulfate and sulfuric acid. An electric current is passed through the solution, and copper… Read More; nickel
· The electrorefining process of the non-commercial Cu anodes was tested on the enlarged laboratory equipment over 72 h. Cu anodes with Ni content of 5 or 10 wt.% and total content of Pb, Sn, and Sb of about 1.5 wt.% were used for the tests. The real waste solution of sulfuric acid character was a working electrolyte of different temperatures (T1 = 63 ± 2 °C and …

· Electrowinning is defined as the cathodic deposition of metal, in this example copper, from a copper bearing solution by the passage of an electric current current using an insoluble anode. For copper the electrowinning …
Electrorefining is widely used for the purification and production of copper that is suitable for electrical applications. Such plants exist throughout the world on production scales between 1000 and 100 000 t/a. In an electrorefining process, the anode is the impure metal and the impurities are lost during the passage of metal from the anode ...
· The electrorefining is at the heart of not only copper purification, but the production of sodium hydroxide and chlorine. In the electrolytic refining of copper, a thin sheet of high-purity Cu serves as the cathode. The blister copper plates are taken and used as anodes in an electrolyte bath of copper sulfate, CuSO4, and sulfuric acid H2SO4.

· Abstract A new smelting process of Ti comprising magnesiothermic reduction of TiCl4 into liquid Bi and separation of Ti from Bi by electrorefining was proposed by our group. In this study, electrorefining of Ti from Bi–Ti alloys was investigated at 700 °C using a Bi–Ti alloy anode and a Ni cathode in equimolar NaCl–KCl to which 1–5 mol% of TiCl2 was added. On the alloy …
