Once introducing any technology modification in flotation ore processing, the critical aspect is the correct assessment of its influence on achieved production outcomes. The prognosis of upgrading parameters in industrial scale is based on scaling up laboratory results involving algorithms. In the latest years, the prediction of ore beneficiation results is based on mineralogical analysis are included. In this paper the influence of modification of cleaning flotation reagent regime on upgrading effectiveness of copper sulphide minerals in one of KGHM plant has been described. The laboratory research has been conducted with addition of low-saccharified maltodextrine as a flotation support reagent aimed to maximize the concentrate grade. The assessment of influence of maltodextrine as an additive of regular used flotation reagent on upgrading effectiveness in industrial scale has been performed. For interpretation of change in the upgrading effectiveness, the relationship between concentrate grade as the function of ore grade and recovery has been selected. KEY WORDS: copper sulphide minerals, flotation, maltodextrine, upgrading effectiveness
