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 ].
