Copper production in Brazil has advanced today, mainly thanks to Vale's efforts to respond to the higher volume of concentrate production, thus, copper began to have an important weight in the value of Brazilian mineral production, standing third, as well as the country's trade balance. Vale in 2014, accounted for the bulk of production, of which 98 thousand tons were obtained from the exploitation of Salobo mine and 110 000 t in the Sossego mine, hence the relevance to this study. This paper presents the technological characterization study of copper concentrate produced by Sossego mine (VALE), located in the southeast of Pará, in the Carajás Canaan municipality. The deposit is located in a regional shear zone WNW-ESE attitude / 75ºSSW that puts in contact gneissic rocks of the Xingu Complex, to south and supracrustals of the Grão Pará Group, to the north. The mineralization comprises a late stage of hydrothermal system and is represented by chalcopyrite (CuFeS2), which is accompanied by minor amounts of pyrite (FeS2) and siegenita ((Ni, Co)3S4). More rarely, occur pyrrhotite (FeS), sphalerite (ZnS), native gold (Au), among others, in the form of small inclusions in chalcopyrite. The research aimed to investigate and determine some physical properties of the copper concentrate, enabling the provision of new technological information to suit its conditions of handling, transport and processing. The parameters determined were hydrogenionic potential, humidity, granulometric composition, density, the presence of magnetic minerals, mineral composition by X-ray diffraction and minerographic analysis. Research has shown that water in contact with the copper concentrate showed pH 2.82 acid, due to the period in which the sample was stored 18 months. The registered humidity was 9%, with very fine grain size, predominant fraction (<0.062 mm) and weight (95%). The real density of the concentrate was 4,22g/cm³, with magnetite content of 0.37%, its mineralogical composition identified by XRD was, chalcopyrite, chlorite, amphibole, K-feldspar, talc, albite and quartz, as well as its minerográfica composition consists of chalcopyrite up to 90%.
