and copper-molybdenum ores are relatively simple and usually involve lime as a modifier, xanthate as the primary collector, and a secondary collector that includes dithiophosphates, mercaptans...) are typically used in the flotation of porphyry copper and copper molybdenum ores[6]. In copper flotation plants, an increase of 1%-2% in recovery and/or grade is economically remarkable. In this work, reagent......
