Effect of Reagent Regime on Flotation Performance of Refractory Oxidized Copper Ores Containing a High Content of Slime

Abstract:

The study aimed to explore appropriate flotation reagents to recover copper minerals from a high content of slime and refractory oxidized copper ores. Based on the research on the properties of the material, the reagent regime was investigated and a technological flowsheet consisting of one roughing flotation, two concentrate flotation, three scavenging flotation and one concentrate-scavenging flotation was adopted to perform the closed circuit floatation experiment. The optimum depressor of flotation experiment was determined as CHO, activator as (NH₄)₂SO₄ and collector as isoamyl xanthogenate. Under such a condition of reagent types and their appropriate reagent dosages, a copper recovery of 75.03% with a concentrate grade of 18.01% was obtained.
