Research on New High Efficiency Recovery Process for Complex Refractory Copper Slag Resources

Abstract:

The chemical components, dissemination characteristics and flotation behaviour of copper slag have been investigated through chemical analysis, X-ray powder diffraction (XRD), electron microscopeand flotation tests. These results show that the converter copper slag from Hubei, China, is refractory resource owing to its complex composition and mosaic relationship. Copper, iron, and other minerals are closely intergrowth in it. The electron microscope pattern and particle analysis tests demonstrate that the particles of copper are fine and unevenly disseminated in the slag. The proper grinding fineness, types of collectors and collector dosages have been determined through the flotation condition tests. The closed-circuit test is enforced by using the new machine-column joint beneficiation process. As a result, a copper concentrate grading 37.14% at a recovery of 94.75% is obtained. The test result demonstrates that this beneficiation process can treat the complex refractory copper slag effectively.
