The recovery of selenium from Iranian sar-cheshmeh copper anode slime has been investigated. Copper anode slimes are containing varying precious metals, such as: gold, silver, selenium and tellurium. They are being extracted as a by-product in the production process. Arsenic and antimony that present in anode slimes dissolved in 0.4 M KOH. Then, the alkaline roasting of anode slimes in the pres...

however, the conventional gold recovery process is cyanidation, due to the recent environmental laws; researchers are looking for alternative methods for the recovery of gold. furthermore, the copper anode slime is one of the most important secondary sources of gold (about 1200 ppm). so, the main objective of the current work is gold separation from copper anode slime as a rich secondary source...

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...

The aim of this research is to get a better understanding of the electrolytic refining process in order to yield the anode slime. Three types of secondary copper anodes are electro refined in an electrolytic system, where the electrolyte is an acid of copper sulphate solution. As a result of the electro-refining process the anode slime has been gained as secondary product. The experimental ...

This paper addresses investigation of the corrosion behavior of copper bearing anodes with high nickel content. Anodes are produced from different solid wastes formed during the copper or nickel row materials treatment. Nickel content in anode samples had values up to 10 mas %. The content of tin, lead and antimony was up to 1 % for each of elements. Sulphuric acid solution, concentration of 17...

anode slimes are a by-product of the electrolytic copper refining process, which contain the precious and other important metals .in order to find a suitable method for treating these materials it is necessary to know their phase composition. for the separation of various phases from the complexmixture of copper anode. slime, the slime is leached in various steps and the residues of each step a...

Background Bioelectrochemical systems (BESs) enable recovery of electrical energy through oxidation of a wide range of substrates at an anode and simultaneous recovery of metals at a cathode. Scale-up of BESs from the laboratory to pilot scale is a challenging step in the development of the process, and there are only a few successful experiences to build on. This paper presents a prototype BES...

Copper and silver are antimicrobial metals, on whose surface bacteria do not grow. As our paper demonstrates, this commonly reported antimicrobial property does not apply to electrochemically active, electrode respiring bacteria. These bacteria readily colonize the surface of these metals, forming a highly active biofilm. Average anodic current densities of 1.1 mA cm 2 (silver) and 1.5 mA cm 2 ...
