摘要: The present invention is concerned with a method for the substantially selective extraction of tellurium from copper electrorefining slimes. comprises maintaining molar ratio Ag/Se, Ag/S or Ag/Se+S at value about 2 less in slimes during leaching thereof an autoclave. excess selenium and/or sulphur allows formation Ag Se S, which remains insoluble autoclave leaching.
