High Pure Tellurium Powder from Anode Slime

The process includes electrolytic preparation of greater than 99.5% pure tellurium powder from copper refining anode slime with simultaneous removal of lead without affecting the precious metals recovery.

High pure tellurium powder for solar cell, electronic applications and alloying element.

• High pure tellurium powders are produced which is a more profitable product compared to other common metals.
• Load on the precious metals recovery unit is reduced owing to the removal of lead and reduction of mass.
• Precious metals in the anode slimes are not lost in the tellurium recovery process.
