Practical Ore Microscopy and Mineralography is concerned particularly with information obtained from reflected light microscopy of opaque minerals. A review of the mineralographic microscope is provided at the outset, however familiarity with both the petrographic (transmitted light) and mineralographic (reflected light) microscope is a basic premise of the course. Segments of the course that follow are each more-or-less stand-alone.
The course places considerable emphasis on the identification, description and classification of textures because of the enormous practical implications of ore textures to mineral beneficiation and ore genesis. Specific topics such as paragenesis, exsolution and sulfide metamorphism and sulfide phase equilibria will be of concern to those with specific interests. A variety of practical concepts related to ore microscopy (liberation, modal analysis, textural case histories, reconciling mineral proportions and assays) are discussed that pertain particularly to mineral beneficiation.
Finally, a series of exercises are described that relate to information obtained from ore microscopy studies. These exercises involve topics such as: sampling of particulate ore material, changing volume percent to weight percent (and vice versa), point count and grain counting, calculating mineral formula from chemical analysis, regression as a means of determining precious metal hosts in an ore, mass balance procedures involving modal (volume) percentages of minerals and assays of metals.
