ABSTRACT:
A process for separating selenium and tellurium values from each other by heating a solution containing both to a temperature and for a time period, in the presence of concentrated sulfuric acid under substantially anhydrous conditions, sufficient to precipitate the tellurium values. The process is primarily applied to decopperized copper anode slimes by first leaching such slimes with concentrated sulfuric acid under the specified conditions, separating the liquid and solids phases, and then removing the tellurium from the solids phase by a water leach.
