Abstract

The research aims mineralogical characterization and determination of bismuth or the presence of bismuth minerals that are associated with copper ores, as they occur in the Cobriza site. The method is polarization microscopy reflected light. As a result of microscopic study, metal ores and the relationships between them were identified in order to meet existing mineral phases in the reservoir. Mineralogical set consists of chalcopyrite, pyrite, arsenopyrite, Löllingite, pyrrhotite, sphalerite, native bismuth, bismuthinite, tennantite, galena, magnetite, hematite, goethite, marcasite, native silver and red silver. The samples studied minerals containing bismuth, which are preferably as bismuth sulfides (bismuthinite) and Bismuth. The native bismuth generally occurs as free grains of smaller sizes to 60 microns; which is altered to bismuthinite having sizes less than 20 microns.
