The planning method of an experiment investigated the influence of various factors on flotation process of the oxidized copper ore with a preliminary sulfidization by the modified reagent. Dependence of copper extraction in a flotation concentrate was received from consumptions of sulfidizer and collector, pulp agitation time with a sulfidizing reagent. A mathematical model of process was received.The optimal conditions of flotation providing the copper extraction in flotation concentrate at a level of 85,12 % were determined with this model %K oxidized copper ore %K ore processing %K sulfidization %K flotation %K mathematical model %U https://hrcak.srce.hr/index.php?show=clanak&id_clanak_jezik=327738
