X-ray microtomography and autoemission electron microscopy - new possibilities for studying finely dispersed gold ores

An experimental investigation of gold-quartz-sulfide ore occurrences (Verhneniyayuskoe 2 and Niyahoyskoe 2) located in the Polar Urals was held by methods of X-ray microtomography and autoemission electron microscopy. Different shooting modes and image analysis were tried. The three-dimensional images of the internal structure of ores and distribution of fine gold in them were obtained. The possibility of study of submicron gold morphology is discussed.
