This paper presents an automatic system for mineralogical and textural characterization of iron ore samples based on a fully automated single scanning electron microscope and point counting analysis. It employs a motorized and computer-controlled multiple sample stage. Mosaic images covering large areas of polished sections are acquired to measure the volume/weight fraction of mineral compositions (phase fraction calculation is based on user-defined density per phase). Different classifiers discriminate compact and non-compact hematite, polycrystalline and monocrystalline particles, and identify particles as granular, lamellar, and lobular. The entire process is automatic and produces a full pdf report containing typical images and the quantification of mineral and textural phases. This study represents an expedient method to prepare well-polished samples and analyze them in a timely manner that can allow for quicker results in process mineralogy.
