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...

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...

SMM operates an original slime treatment process for recovering precious metals and other metals (l'e,Se,Sb,Bi)from the copper and the lead anode tankhouse slimes. In recent years, the amount of slimes has increased and the pyrometallurgical processing units capacity became the bottleneck of the entire plants. For the expansion of the plant, new pyrometallurgical facilities, incorporating a BBO...

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 ...

Processing of anodic slimes from an Egyptian copper electrorefining plant, exhibiting high contents of copper, lead, tin and silver has been presented. The proposed hydrometallurgical process consists of two leaching stages for extraction of copper with H2SO4 – O2 and silver with thiourea – Fe. Pyrometallurgical treatment of the leaching solid residue for production of Pb-Sn soldering alloy was...
