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 and Collins, 1976 ).

10/12/2018· Within copper mining and extraction, the resulting tailings usually account for a high proportion (up to 99%) of the mined ore (). Submarine tailing disposal is considered to be a viable option as the tailings are not visible on land, may be more stable on the ocean floor and are less likely to oxidize in the submarine environment.
