copper electrorefining process anode slime Construction Waste Crusher Construction waste refers to the construction, construction units or individuals to construct, lay or demolish all kinds of buildings, structures and pipe networks, etc., and generate the spoil, spoil, waste, residual mud and other wastes generated during the repairing process.
Combining conventional electrochemical measurements, laser‐based visualization and digital image processing, the movement of anode slime, its spatial distribution and path of falling during the copper electrorefining process were investigated in a laboratory scale cell. Two types of anode slime, small agglomerates and fine particles were ...
efficiency of copper electrorefining. Declining concentrate grades cause larger impurity levels in anodes, thus creating larger quantities of slimes in the refining process. In order to investigate the characterization methods for adherent anode slimes in copper electrorefining, experiments were conducted for the Boliden
Copper electrorefining (CuER) is the principal method for producing >70% of high or % pure copper cathodes from 9799% pure blister/fire refinedscrap copper anodes. While the inert and most of less soluble impurities settle as anode slime/sludge, other soluble impurities, particularly the metalloids (group VA/15 elements or Q: As, Sb and Bi) and some transition metals (Mt) codissolved ...

The treatment of copper scrap consisted of copper smelting and converting, copper electrorefining, anode slimes purification by H 2 SO 4 leach (to remove Cu + Ni), doré smelting and silver electrorefining in a Thum cell, gold mud leaching with aqua regia, gold reduction with SO 2, and selective precipitation of red and yellow salts.
Copper Electrorefining Process Anode Slime. Copper anode slimes the byproduct of the copper electrorefining process have been the subject of extensive investigation for recovering precious metals viz Au Ag Pt and Pd in addition to. Send Email: [email protected] Leave Message Chat Online.
The present invention is concerned with a method for the substantially selective extraction of tellurium from copper electrorefining slimes. The method comprises maintaining a molar ratio Ag/Se, Ag/S or Ag/Se+S at a value of about 2 or less in the slimes during leaching thereof in an autoclave. The excess of selenium and/or sulphur allows the formation of Ag 2 Se or Ag 2 S, which remains ...
Anode slime samples were collected from the bottom of the electrolytic cells during the electrorefining of copper. These samples were sieved through a mm sieve to remove large inclusions of copper and other foreign material present in the slime. A representative sample of the feed slime was analysed for Cu, Pb, Sn, Zn, Ni, Fe,
A method of increasing the extraction of tellurium from copper electrorefining slime comprises leaching the slime with dilute sulphuric acid in a reactor under a partial oxygen pressure of up to 150 psi and at an elevated temperature between about 100° and 200° C. until copper, nickel and substantially all of the tellurium is dissolved, thereby forming a leach slurry, and contacting the ...
Aug 25, 2016· An innovative copper electrolytic cell was designed with its inlet at the cell top and its outlet near the cell bottom, in opposite to conventional electrolytic cells. It was modeled in COMSOL Multiphysics to simulate copper electrorefining process. Unlike conventional electrorefining cells, downward electrolyte flows are more dominant in the fluid flow field in this cell, which leads to ...
Anode slime is a byproduct from copper or lead electrorefining process. The copper/lead anode slime usually contain As, Sb, Bi and precious metals like gold and silver. Smelter of anode slime is most likely divided into two groups by the two different recovery processes based on its property and treatment capacity, pyrometallurgy and ...
Anode slime is the insoluble product deposited at the bottom of the electrorefining tank during electrorefining of copper. It generally contains Cu, Ni, Se, Te, Ag, Au, platinum group metals (PGM), Pb, Ba, Fe, etc. Owing to the presence of valuable metals and metalloids in the anode slime, numerous approaches have been made by the researchers to extract them following pyro, pyrohydro ...
Apr 02, 2004· A new approach for the treatment of copper electrorefining anode slime based on hydrometallurgical route involving sulfuric acid leaching with additives such as manganese dioxide and sodium chloride has been developed at National Metallurgical Laboratory (NML), Jamshedpur, India.
