the application of ore microscopy to certain industrial problems commonly can serve to save millions of dollars for industrial firms. for 12 years, hagni and students working with him served as the process mineralogy group in the pyrometallurgical research center that was funded by the u.s. bureau of mines, headquartered at umr, and conducted pyrometallurgical research throughout the united states.,automated ore microscopy based on multispectral measurements of specular reflectance…,ore microscopy, as a tool for the study of ore deposits, became a mature technique about a century ago (or at least by the 1930s, e.g. schneiderhöhn and ramdohr (1931)). reflected light microscopy has been widely applied to support ore geology, mineral exploration, and ore processing all along the second half of the twentieth century.
