Copper Tailing - an overview ScienceDirect Topics

Although copper slag had trace amounts of heavy metals like As, Cd, Cu, Cr, Pb and Zn in its composition, they were found to be stabilized due to their encapsulation by the bitumen present in asphalt mix [72]. Copper tailing is the waste rock remaining after ore has been processed to remove the copper.

REPROCESSING OF THE OLD FLOTATION TAILINGS

2009-3-21  The tailings contain 60 to 70% of SiO2, 10 to 17% of Al2O3and pyrite 5 to 8%. Flotation tailings reprocessing consisted of acid leaching followed by re-flotation of the leach residue. Leaching of the tailings resulted in leach liquors containing Cu2+ ions from 50 to 580 ppm.
