Recovery of Copper from a High Content of Slime and Refractory Copper Oxide Ore by Flotation

Abstract:

The study aims to recover copper minerals from a high content of slime and refractory copper oxide ore by flotation process. Based on the research on the properties of the material, the grinding fineness and reagent system are investigated and a technological flow sheet consisting of one roughing flotation, two concentrate flotation, three scavenging flotation and one concentrate-scavenging flotation is adopted. The optimum parameters of flotation experiment are determined as grinding fineness of 90%, dosage of CHO at 200 g/t, dosage of Na2S at 800 g/t and dosage of isoamyl xanthogenate at 1200 g/t. Under such a condition, a copper recovery of 75.03% with a concentrate grade of 18.01% is obtained，which provides a new way for separating the refractory copper oxide ore attached high content of slime.
