Selective Separation and Recovery of Tellurium from Copper …

Tellurium is a critical metalloid element that is majorly produced from copper anode slime and is widely consumed in solar energy systems. In this research, a sustainable recovery of tellurium from copper anode slime obtained from Sarcheshmeh Copper Complex, Iran, was investigated. At first, the dissolution of tellurium and other …

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 ].
