The use of copper anode slime (CAS) for the removal lead, bismuth, and arsenic is key to recovering precious metals. In this paper, vacuum differential gravimetry experiments combined with thermodynamic equilibrium calculations reveal effects temperature, system pressure, carbon concentration on interactions among Pb, Bi, As during reduction. content a direct factor limiting reduction reactions...

Passivation behavior of high silver containing copper anodes was investigated using slowly cooled Cu- 1%Ag different lead (Pb) concentrations. The addition Pb distributes in the phase and reduces amount that is solidly soluble and, thus, generates a fine powder on anode surface which main contributing factor passivation. Electrorefining experiments were conducted synthetic electrolyte 40 g/L Cu...

The mechanism of selective separation antimony from copper anode slime leachate is studied. Density functional theory used to calculate the unit cell energy, band structure, density states, number charge distributions and overlap populations SbCl3 hydrolysates SbOCl, Sb3O4Cl Sb4O5Cl2, these are studied by infrared spectroscopy. pathways for formation Sb4O5Cl2 in water, ethanol ethylene glycol s...

the recovery process of selenium from iranian sar-cheshmeh copper anode slimes employing hydrometallurgical methods has been investigated. the copper anode slimes are made up of those components of  the anodes, which are not soluble in the electrolyte. they contain varying quantities of precious metals like gold, silver, selenium and tellurium. they are being extracted as a by product in the co...

a high percentage of world copper production is obtained from porphyry copper reserves, these reserves are characterized by: very high tonnage, greater horizontal dimensions than vertical, association with stock like intrusion masses, dispersed minerals in the porphyry mass and in its neighbor rocks, intense sericitization and inplace silicification. the porphyry coppers are concentrated by flo...

Electrolytic copper refining makes it possible to obtain high purity metal, so the analysis of main ways impurity transition into electrolysis products is an actual problem. If solved, process can be controlled when changing composition raw materials and, as a result, content impurities in anodes. This paper uses comprehensive and synchronization large array data on concentrations various media...
