  • Multivariate Image Analysis in Mineral Processing

    Abstract. In several process industries including mineral processing, where the materials are solids or slurries, some important measurements cannot be obtained using standard instrumentation (e.g., flow, temperature, pressure, pH, power draw, etc.), but can be visually appraised, and could be automatically quantified using machine vision techniques.

  • How to Determine Mineral Liberations by Image Analysis

    A slicing effect which modifies mineral interrelations is, however, produced by mounting and polishing ore pieces in briquettes. Nevertheless image analysis data obtained from polished sections can be evaluated without corrections to determine relative mineral behaviours, and with mathematical corrections to determine absolute mineral behaviours.
