This paper discusses studies conducted to determine grinding parameters for optimum liberation of sulfide values from bulk sulfide concentrate produced from Missouri pb ore concentrator tailings; optical microscopy was used coupled with image analysis. The major sulfide phases present in the ground mineral particulates are marcasite, pyrite, sphalerite, galena, chalcopyrite, siegenite, and bravoite. Results showed that the base metal minerals were liberated by grinding to 74 um (200 mesh), but the siegenite and bravoite required grinding to 20 um or less to achieve liberation. Both the experimental method and results are presented.
