Behavior of platinum metal concentrates under autoclave conditions

Behavior of platinum metal concentrates under autoclave conditions Dressing processes of platinum metal concentrates (CP-1 and CP-2) in acid and alkaline media under autoclave conditions were studied. The optimal recovery conditions (time-, temperature-, and concentration-related) of impurity elements were found for the temperature range under study. It was demonstrated that the predominant changes occur during the first 30–60 min. Use of reducing agents can preclude transfer of noble metals into solution in leaching of impurity elements. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Applied Chemistry Springer Journals

Abstract

Dressing processes of platinum metal concentrates (CP-1 and CP-2) in acid and alkaline media under autoclave conditions were studied. The optimal recovery conditions (time-, temperature-, and concentration-related) of impurity elements were found for the temperature range under study. It was demonstrated that the predominant changes occur during the first 30–60 min. Use of reducing agents can preclude transfer of noble metals into solution in leaching of impurity elements.
