In this paper are presented the results of selection of flotation collector for porphyry copper ore from “Severni Revir” ore deposit in Copper Mine Majdanpek. The selection was performed between two collectors (Z11 and AP3404) with 3 different dosages (25; 35; 45 g/t) and their mixture with SKIK in different mass ratio. The VIKOR method was applied for the rating of 10 alternatives by 5 criteria: mass yield, copper grade in concentrate, sulfur grade in concentrate, copper recovery, and collector expenses (dosage and price). Based on the results of the analysis, alternative A8 which represents the mixture of three collectors Z11, AP3404, and SKIK with following dosage 20+8+8 g/t was selected as the best alternative.enPorphyry Copper OreFlotationCollectorSelectionVIKOR MethodconferenceObject
