Waste-free separation and recovery of copper telluride slag by
Copper telluride slag contains tellurium, copper, silver, selenium, oxygen, sulfur, etc., and is extracted via hydrometallurgical processes, which account for approximately 80% of the global tellurium production and consists of several steps, as shown in Fig. 1. There are two main problems for copper telluride slag recovery.

Solar powers demand for rare tellurium
It is estimated that this refinery produces roughly 60 metric tons of the solar panel ingredient each year. In fact, nearly all tellurium currently produced comes from copper refining and the USGS said this helps to reduce the geopolitical risks of sourcing this solar metalloid. "Regardless, demands for tellurium, particularly as the global ...

Tellurium in the Copper Supply Chain
The world copper supply chain can supply tellurium needs for the near term. Without new or bigger U.S. smelters and refineries, Te will be produced elsewhere if sourced from slimes. Domestic Te supply will only increase if more is captured during mineral processing. Losses during slimes processing are not understood which impacts allied production.
