tellurium copper lead

Tellurium copper Wikipedia

Tellurium is usually added to copper to improve machinability ("free cutting"). ASTM specification B301 has 0.5% tellurium; at concentrations of up to 0.75% machinability is improved whilst electrical conductivity and hot working behavior is maintained. Mechanical properties are similar to tough pitch copper, whilst machinability is similar to brass the alloy's hardnesses are increased by precipitation of copper telluride .

Lead-Tellurium Alloy (UNS L51123)

Aug 07, 2013· Tellurium is often used by metallurgists to produce metal alloys. It can be a minor additive for copper alloys, reducing copper's conductive properties, thereby making the product easier to work. When tellurium is added to lead alloys, the durable product is

Extraction of tellurium from lead and copper bearing feed

Jan 01, 2018· 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

Tellurium GGX Gold Corp.

The predominant source of tellurium today is from anode slimes or sludges produced during the refining of copper and lead ores. It takes approximately 500 tons of copper ore to produce 1 pound of tellurium. Tellurium concentrations in porphyry copper deposits vary widely and can be as high as 6,000 ppm Te, but are typically less than 1 ppm Te.
