Tellurium - an overview | ScienceDirect Topics

Tellurium is recovered from the solution by cementation with copper. Copper telluride is leached with caustic soda and air to form a sodium tellurite solution. This solution, along with excess free caustic soda, is then electrolyzed in a cell using stainless steel anodes to produce tellurium metal (Kirk-Othmer, 1997).

Electronic Scrap - an overview | ScienceDirect Topics

Some electronic scrap has for years been recycled to copper smelters, and therefore its PMs content is eventually recovered within the Cu refinery anodic slimes (Beke, 2001).There were plants, however, primarily dedicated to the treatment of electronic scrap. One such plant, using conventional pyrometallurgy, was the US Metals Refining (USMR) Company (Amax) plant in Carteret, New Jersey (Fruh ...
