Recycling of tellurium via copper smelting processes

Tellurium is found in primary copper ores, and most of the tellurium produced in the world comes from processing of copper anode slime, which is a by-product formed during electrolytic refining of copper. Traditionally, tellurium has been mostly used as an additive in copper, iron, steel and lead alloys [ 1, 2 ].

Can someone clue me in to teryllium?

Tellurium is used in copper and lead production to improve durability and strength as well as reduce corrossion. I would imagine that his name for the material was derived from that in some way. TeI3 only exists in molten form, where it becomes a conductor. When added to most metals it also makes them malleable. 2.

Plating C14500 tellurium copper

Hi Jeff. There isn't a lot of tellurium in there, it's 99.5%+ copper. So I suspect, but don't know for sure, that the conventional tarnish preventative treatments for copper -- like sodium benzotriazole and chromates -- will work on tellurium copper.

In Our Element: How Do You Heat Treat Copper Beryllium Parts?

Heavy sections (above about one inch) usually require 1-3 hours. A heat up time of one hour per inch of thickness must be added to the soak time. Because most salts will attack copper beryllium at temperatures in the solution annealing range, solution annealing should not be performed in a salt bath.
