The anodes are cooled rapidly to about 510°C and promptly placed in a chamber for cooling under controlled condi tions to 200°C. This pro cedure prevents the anodes from crack ing during the j3 Ni3Sz ~ j3' Ni3Sz phase transformation at 505°C. This step takes about 25 hours. The anodes are then electrolyzed at 240 A/mz.
extracted from the anode sludge created by the electrorefining process. Copper concentrates often contain precious metals like Au and Ag. Recovery of these metals from anode slime is economically attractive and also it is environmentally. friendly. Temperature plays a critical role on dissolution of gold. from copper anode slime.

Process for the flotation of anode slime from copper electrolysis comprising subjecting the anode slime, as a preliminary treatment, to attrition treatment in combination with a copper leaching treatment in a medium of an acid solution. The floated material obtained from the flotation is continuously subjected to three processes of roasting, melting and cupellation in a .
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 .
Apr 16, 2019· The anode slime produced from copper electrorefining is an important byproduct in the recovery of valuable metals, especially precious and rare,2,3 Treatment processes of copper anode slime include traditional pyrometallurgy electrolysis, hydrometallurgy and a flotationmetallurgy combination process.

· Copper electrorefining (CuER) is the principal method for producing >70% of high or % pure copper hodes from 9799% pure blister/fire refinedscrap copper anodes. While the inert and most. 2 Highly Influenced View 4 excerpts, cites background Pressure leaching of decopperized copper electrorefining anode slimes in strong acid solution
Phelps Dodge Mining Company El Paso Operations 850 Hawkins Blvd., El Paso, TX 79915. ABSTRACT In pressure oxidation leaching of copper anode slimes, more than 65% of the tellurium is coextracted during decopperizing. About 10 – 15% of the selenium is also dissolved imultaneously by severe leach conditions.
Abstract Anode slime, a byproduct from the process of copper electrorefining into the copper hode, contains several valuable elements that can be extracted after Cu and Pb separations. Another alternative route for extracting the precious metals is still needed in terms of gaining more economical route.
Smelting plant is designed to produce 200,000 tones of copper hode per year. PT. Smelting then carried out three times expansion in 2004, 2006, and 2009 so that production capacity increased to 300,000 tones of copper per year. PT. Smelting use Mitsubishi technology in Copper smelting process and ISA technology in copper refining process.
Matte from the smelting furnaces is, batch wise, fed to converters whereupon the sulphur content is reduced in a slag blowing and a copper blowing step. The copper is deoxidised by ammonia addition in an anode furnace whereupon the copper is .
· The raw material of copper telluride (Cu 2 Te) precipitate from anode slime processing used in the present study was obtained from Tongling Nonferrous Metals Smelter in China. It was dried at 120 °C for 24 h and then ground into fine particles with an average size of below 300 μm for further leaching experiments and analysis.
