Anodic slimes formation in copper electrowinning

Copper electrowinning: theoretical and practical design

The electrowinning of copper ions derived from leaching, or solvent extraction is a significant contributor to the global copper commodity supply. The process of electrolysis for copper was first developed in the late 19th century and despite numerous advancements in technology the principles and basic equipment remain the same. The first part of this paper deals with the theoretical requiremen...

Processing of Copper Anode-slimes for Extraction of Metal Values

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...

Anodic Formation of Ordered TiO

characterization of copper anode slimes from bicc

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...

Anodic oxide formation on aluminium-terbium alloys

Aluminium terbium alloys were prepared by simultaneous thermal evaporation resulting in a thin film library covering a 5 to 25 at.% Tb compositional spread. Synchrotron x-ray diffraction (XRD) proves all of the alloys to be amorphous. Scanning electron microscopy (SEM) measurements reveal the structural changes upon increase in Tb content with the formation of small, Tb-rich segregations right ...
