This investigation was directed toward a detailed study of the comminution of complex sulfide ores from the eastern United States. The first part deals with laboratory batch grinding experiments in which several different ore samples are characterized in terms of rate of breakage and breakage distribution functions. Using these parameters, the batch grinding experiments are simulated by the estimill program. In the second part, both pulverized and uncrushed ore samples are examined using an optical microscope, with the images processed by a computer. A software package named the general image processing system (gipsy) was adapted and expanded to process the optical images and to characterize the ore samples and mill products. Finally, the image analysis data are compiled to determine the degree of liberation of the various minerals present in the complex sulfide ores.
