Copper anodes from the converter process are dissolved electrolytically using an acid copper sulphate solution as an electrolyte. The products of this operation are pure copper cathodes and an anode slime which may contain gold and small quantities of the platinum group metals. The cells are constructed of rubberlined concrete.
Firerefined copper can be cast into either anodes, which are used during electrolysis, or billets. The anodes are submerged in a sulfuric acid solution containing copper sulfate. As copper is dissolved from the anodes, it deposits on the cathode. Then the cathode copper, which is as much as percent pure, is extracted and recast.

Aurubis AG (formerly Norddeutsche Affinerie AG) is listed on the stock exchange and is the largest copper producer in Europe (the second largest in the world) and the largest copper recycler worldwide. Its headquarters is in Hamburg, Germany. After the acquisition of the Belgian copper producer Cumerio by Norddeutsche Affinerie AG on 18 February 2008, the company rebranded itself as Aurubis ...
The combination of flotation and metallurgical processing to treat copper anode slime produces approximately 1400 tons of flotation tailings every year in Yunnan Province. These tailings contain a large amount of valuable metals.
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 ...
uranium ore processing copper anode There should be no processing of the uranium ore and the mine should only process copper and precious .. modifiions to the existing metallurgical plant include an additional anode furnace, additional.
Processing Technology o f Copper Ore "Low grade, many impurities, high oxidation rate, and difficult to separate" are the most appropriate descriptions of China's copper resources. It's estimated that more than 40% of China's copper resources are hard to utilize.

are copper scrap, WEEE scrap of different qualities, especially printed circuit boards, dust, slag, lead production alloys containing precious metals, and anode slime from copper electrolysis. Depending on the purpose, different watercooled lances are used for melting, oxidation, reduction, or flue dust feeding.
Mineral Processing Plants Magaldi Group. 19 行 Mineral Processing Plants Home / Expertise / Mineral Processing Plants When processing minerals such as copper, iron ore, niobium, lead and others, it is necessary to carefully handle very hot, abrasive and fine valuable materials in a very tough environment.
Copper Anodes: In copper processing, a copper anode is an intermediate product from the smelting furnaces which is used as a copper source from which to make copper cathodes during electrolysis. In electrolysis, it is the positive terminal. Oxidation occurs at the anode. The anode is replaced when it's been eroded too far and risk falling apart.
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
content of anode slime. The main phases in the anode slime were copper and lead sulphates as well as coppersilver selenides. NiO was shown to be the major Nibearing phase in the adherent slime. Nickel, tellurium and lead had the strongest, whereas arsenic, selenium and antimony had the weakest tendency to report to the anode slime. Keywords ...
The fire assay gravimetry is an old and classical method. It is one of most commonly used and most effective methods for the separation and analysis of precious metals due to strong representativeness, high accuracy and good stability. However, the fire assay gravimetry also has some disadvantages such as long analytical procedure and systemic lower analytical results (especially for silver).
During the electrorefining process, precious metals like gold, silver and Selenium present in the anode settle down at the bottom of the cells along with other impurities. This collection is known as anode slime and it is subjected to atmospheric leaching for recovery of copper filtered, dried and bagged.
