Abstract Aiming at the recovery of copper from smelting slag, a flotation approach was studied. It was found that this slag composed of fine particles with complex association and distribution, in which bornite was the main copper-bearing mineral after a detailed mineralogy analysis via polarizing microscope, SEM and XRD. Consequently, otation was attempted to recycle Cu in …

A smelting plant in Bor extract copper from copper ores and copper concentrates by a pyro metallurgical process. During years of operation, a considerable amount of copper slag has been generated as a by-product and has been dumped. Copper contents in these slags are as high as 0.6 up to 0.8%. As such, this slag could be considered as a secondary source for copper re …
