  Copper Refining Electrolyte and Slime Processing - Emerging …

  2013111 · 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 …

  Tellurium, from Copper Anode Slime to High Purity Product: …

  2020106 · Tellurium is a rare metalloid that is vastly produced from copper anode slime, which is a by-product of the copper electrorefining process. Choosing the proper recovery method strongly depends on the slimes composition, mineralogy, and tellurium concentration. In addition, correctly selecting the right method of leaching, purification, …
