beneficiation of copper tailings

Copper Tailing - an overview | ScienceDirect Topics

Copper tailings are a finely ground waste after copper mineral has been extracted from the ores during beneficiation. Similar to CS, the use of copper tailings as a geotechnical material has also been reported in the literature, but on a relatively smaller scale (Collins and Ciesielski, 1994; Gupta and Thomas, 2013; Nitish et al., 2013; Miller ...
