Platinum - Palladium Flotation - 911 Metallurgist

24-06-2017  Because most of the platinum-group bearing sulfides occurred as fine grains and required grinding to approximately 200-mesh for liberation, flotation was investigated as a means for concentrating the metal values. The low concentration of metal values in the ore made it difficult to obtain consistent analytical results.
