Copper electro-refining (Cu-ER) is the principal method for producing >70% of high or 99.97% pure copper cathodes from 97-99% pure blister/fire refined-scrap copper anodes. While the inert and most of less soluble impurities settle as anode slime/sludge, other soluble impurities, particularly the metalloids (group VA/15 elements or Q: As, Sb and Bi) and some transition metals (Mt) co-dissolved with Cu(II).
In electrowinning, a current is passed from an inert anode through a liquid leach solution containing the metal so that the metal is extracted as it is deposited in an electroplating process onto the cathode. In electrorefining, the anodes consist of unrefined impure metal, and as the current passes through the acidic electrolyte the anodes are corroded into the solution so that the electroplating process deposits .

A few years ago, homemade slime (sometimes known as Gak or goop) became all the rage, with all-in-one kits showing up on store shelves and YouTube tutorials saturating iPads everywhere. Perhaps this explosion was the next logical step in a worldwide push to get kids excited about science, technology, engineering and math ( STEM ) careers.
Slime produced during conventional copper electrorefining processes normally contain a large variety of elements, including noble metals (Ag, Au, Pt and Pd) as well as significant quantities of selenium, tellurium, copper lead and nickel.
Silver Refining Process - Outotec. The electrorefining process is continuous except when new silver Doré anodes are loaded in the cells and the crystals of refined silver, silver anode slime and anode scrap is discharged from the cells at the end of the electrolysis cycle.
During the electrolysis process pure copper is deposited on cathode plates and impurities which are soluble fall to the bottom of the cell as anode slimes or sludge. Precious metals (Ag, Pt, Pd), can be extracted from the anode sludge created by the electro-refining process. Copper concentrates can also contain precious metals like gold and silver.
Effect of As, Sb, Bi and Oxygen in Copper Anodes During Electrorefining Proceedings of Copper 2010 1499 ionised water and brushed, to remove remaining anode sludge from the surface of the anodes. In the next step, the electrolyte from each cell is filtered and the collected anode sludge is immediately washed and dried.
I The Science of Slime! It oozes between your fingers when you pick it up, yet doesn''t stick to your skin. It comes in a variety of colors, usually green.
Solid phases in copper electrorefining that originate from anode impurities are referred as slimes. Anode slimes can be classified as adherent, bottom and floating slimes based on their location. These are further divided to primary and secondary slimes based on their formation mechanism (Wang et al., 2011).
The process of extracting copper from copper ore varies according to the type of ore and the desired purity of the final product. Each process consists of several steps in which unwanted materials are physically or chemically removed, and the concentration of copper is progressively increased.
Processing of copper electrorefining anode slime: a review, 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, .
Anode slime, a byproduct from the process of copper electrorefining into the copper cathode, 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.
