Extraction of tellurium from lead and copper bearing feed ...

2018-1-1  The main sources of tellurium in the lead smelting process are copper dross (mass of solid impurities floating on a molten metal), alkaline skimming and rich sliver dross intermediate products (Chizhikov and Shchastlivyi, 1970, Smirnov, 1977, Davey, 1980, Margulis and Zaitsev, 1985). Tellurium accumulates in these byproducts during refining of ...

C14500 Alloy, C145 Tellurium Copper - Concast

C14500, or tellurium copper, has similar mechanical properties to unalloyed, pure copper but with a higher machinability. Thus, the cutting properties of C14500 are enhanced significantly by creating a copper alloy with the addition of tellurium. Tellurium copper is also known for its high electrical conductivity characteristic.
