N2 - Morphology and mineralogy of the copper matte particles oxidized in simulated flash converting conditions were studied by scanning electron microscopy combined with EDA (EDS and WDS) for chemical microanalyses of the phases. The variables used in the experiments were copper grade of 3 mattes, screen size fractions, preheating temperature and the concentration of oxygen of the reaction gas. Analogical structural phenomena as in the intensive oxidation of natural copper minerals were found, but the ground copper matte is less reactive than the concentrates. Coarse fractions of mattes were found to fragmentate effectively with their final particle size of the order of 5 μm, independently of the initial particle size.
