Recovering selenium and tellurium from copper refinery slimes
TL;DR: The significant amount of selenium and tellurium present in copper refinery slimes often makes the recovery of these elements not only desirable, but economically viable as mentioned in this paper, and a variety of processes have been developed to this end, some are more feasible because they recover greater values and are environmentally safer.
