Copper Electrolysis Process Explained It was desired to select an Arizona problem so the treatment of a porphyry copper ore seemed to be one of the most important This kind of ore when treated for the extraction of its copper by mechanical concentration and smelting the methods most generally employed yields 66 per cent or less of its copper ...
Apr 10, 2014· The copper anode slime used in the experiments was provided by one of the copper smelters in China. Before experiments, the original copper anode slime was washed with hot water of 80 °C and then sieved with 100 mesh sieve to remove large particle. And then slurry was vacuum filtered and dried at 120 °C.

Jul 18, 2013· 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 ...
from copper anode slime Recovery of gold from copper anode slimes is a multistages process There are more than 650 operating and planned copper mines, 140 smelters and 250 refineries world wide
Treatment of Waste Copper Electrolytes Using Insoluble and Soluble Anodes Radmila Markovic1, ... during the change depending on the general conditions for the electrolysis as well as electrolysis getting anode copper. The cathode deposit must not be contaminated and the anodes must not be ... the stannic hydroxide and remain in the anode slime.
Anode slime is the byproduct of copper or lead electrorefining process and found in electrolytic cell bottom or on the anode scrap surface. The copper anode slime and lead anode slime usually contain precious metals like gold and silver. Depending on the treatment capacity, process of anode slime recovery is achieved by two different methods ...
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 from copper electrolysis, though a byproduct of copper industry, contains man y valuable and important metals like nickel, copper, selenium, tellurium
Anode: 4OH 4e → 2H2O + O2↑ 2SO42+2H2O 4e → 2H2SO4 + O2↑ After treatment of the cathode surface, the copper layer deposited on the cathode can be peeled off, to obtain a certain thickness of copper sheet. The copper sheet with certain functions is called copper foil.
A process for the removal of lead content in anode slime by subjecting the latter to primary and secondary leach in a medium of an ammonium acetate solution at a temperature not exceeding 80° C. Whereby lead dissolution is maximized and other metals are minimized. Separate the leach solution from the undissolved slime residue, crystallize lead from the separated leach solution and recover the ...
cast into anodes. Those copper anodes are electrorefined in an electrolytic system, where the electrolyte is an acid copper sulphate solution, where a high purity electrolytic copper is produced (>999,9/1000). The slime when submitted to an oxidative leaching process, using sodium hypochlorite and hydrogen peroxide as oxidizing agents, turn ...
Electrorefining of Copper 1. Electrorefining – General Introduction In an electrorefining process, the anode is the impure metal and the impurities must be lost during the passage of the metal from the anode to the cathode during electrolysis, the electrode reactions are, at the anode: M → Mn+ + neand at the cathode: Mn+ + ne→ M
Adherent anode slime samples were collected from the Boliden Harjavalta''s Pori refinery during MarchApril 2014 from 31 different anode cells, one anode lug and one adherent anode slime sample from each. The adherent anode slimes were collected before washing of anodes, at the end of the electrolysis cycle. Then, the samples were
It is also vital in electrolysis, fundamentally to refine copper, nickel and uranium, and it is indispensable in water treatment, the textile fibers manucaturing and galvanizing. Anode Slime. Anode slime is a product obtained from the copper electro refining process.
Nov 23, 2015· In this last video we smelt the dried anode slimes and recover a button of precious metals. This is the third and final installment of our smelting and gold refining series. Email: infoMBMMLLC ...
A wide variety of anode water treatment options are available to you. You can also submit buying request for the abs sensor and specify your requirement on, and we will help you find the quality anode water treatment suppliers. There are a lot off suppliers providing anode water treatment on, mainly located in Asia.
Mar 02, 2010· More precisely, the invention relates to a method and device for treating anode slime obtained from copper electrolysis. In copper electrolysis, the insoluble element of the anodes falls on the bottom of the electrolytic tank as anode slime, from where it is recovered when the anodes .
During the electrolysis the metals present in the anode, which are of lower electrochemical activity than copper, chiefly silver, tellurium, gold, and traces of platinum, are precipitated as slimes on the floor of the electrolysis cells as they are released from the anodes (Table ). Any mercury, which is frequently present in the ore, is ...
