Electrolytic refining is a process of refining a metal (mainly copper) by the process of electrolysis. As far as the mechanism of the process is concerned, during electrolysis, a large chunk or slab of impure metal is used as the anode with a thin strip of pure metal at the cathode.
ELECTROLYTIC REFINING OF COPPER. Introduction. Although copper can be separated from its solution by means of the electric current and the amount so separated varies directly as the current. there is . a . point in each and every solution where on account of the ener8Y given off to the ions, the copper will . be . carried' over in a more or less impure state,depending upon the strength of the
29/12/2017· Electrolytic refining (electrorefining) is a process used to make impure copper pure. Unlike aluminum, copper metal is fairly easy to obtain chemically from its ores. By electrolysis, it can be refined and made very pure—up to 99.999%.

Figure 17.5. 1: The electrolytic purification of copper. In such a cell a thin sheet of high-purity Cu serves as the cathode, and the anode is the impure Cu which is to be refined. The electrolyte is a solution of copper (II) sulfate. Some of the impurities are metals such as Fe and Zn which are more easily oxidized than Cu.
In the electrolytic refining of copper, the impure copper is made from the anode in an electrolyte bath of copper sulfate, CuSO 4, and sulfuric acid H 2 SO 4. The cathode is a sheet of very pure copper.
The soluble impurities go into the solution whereas the insoluble impurities settle down at the bottom of the anode which is known as anode mud. Following diagram shows the electrolytic refining of copper in which anode is impure copper and cathode is thin strip of pure copper while the electrolyte used is the copper sulphate solution.
The refined blister copper is poured into casting molds lined up side by side on the revolving circular table of a casting wheel and cast into anode plates for electrolytic refining. The anode plates are approximately 1m x 1m x 0.05m in size, and weigh 380 kg per plate.

Copper Electrolytic Refining Process. In the electrolytic refining of copper the more electropositive impurities like Fe, Zn, Ni, Co, etc. dissolve in the solution and less electropositive impurities such as Ag, Au and Pt collect below the anode in the form of anodic mud.
Apparatus for electrolytically refining copper by the series process comprises a tank having an inner surface of an electrically insulating synthetic polymeric material that is substantially inert to an electrolyte solution to be contained in the tank and, associated with the tank, baffles for reducing current flow that would otherwise occur around the edges of electrodes when immersed in the electroltye solution.
Typical flow sheet for a copper refinery. The process for electrorefining copper is typical of those carried out in aqueous solution. The electrolyte is copper sulfate (0.7 molar) and sulfuric acid (2 molar) and the way in which the purification of the copper occurs can be seen by considering the metals likely to be found. as impurities :
18/11/2020· Electrolytic copper refining involves two primary components, a sheet of unrefined ore called an anode plate and a smooth, steel sheet called a mother blank. These components submerge into an electrolyte bath and an electrical charge deposits copper atoms from the anode plate onto the mother blank, forming sheets of refined copper.
The refined blister copper is poured into casting molds lined up side by side on the revolving circular table of a casting wheel and cast into anode plates for electrolytic refining. The anode plates are approximately 1m x 1m x 0.05m in size, and weigh 380 kg per plate.

Copper Electrolytic Refining Process. In the electrolytic refining of copper the more electropositive impurities like Fe, Zn, Ni, Co, etc. dissolve in the solution and less electropositive impurities such as Ag, Au and Pt collect below the anode in the form of anodic mud.
In the electrolytic process, copper is electrodeposed to obtain a spongy powder deposit at the cathode rather than a smooth, adherent one. In this feature, it differs from the process of copper refining where a strongly adherent product is desired. Low copper ion concentration and high acid content in the electrolyte favor formation of powder deposits.
An electrolytic copper refinery needed an efficient and reliable way to monitor voltage on more than 700 electrolytic cells used to produce A grade copper. The refining process in this type of plant begins with copper anodes of 99% pure copper plates produced in a copper smelter. These copper anodes are submerged in an acidic copper sulphate solution, between stainless steel “mother
Electrolytic Copper Refining Plant Copper electrorefining entails electrochemically dissolving copper from impure copper anodes into an electrolyte containing CuSO4 and H2SO4, and selectively electroplating pure copper from this electrolyte without the anode impurities.

Electrolytic refining separates copper from impurities by electrolysis in a solution containing copper sulfate (Cu2SO4) and sulfuric acid (H2SO4). The copper anode is dissolved and deposited at the cathode. As the copper anode dissolves, metallic impurities precipitate and form a sludge.
