The properties of copper tailings, a finegrained residue waste produced from beneficiation of copper ore, and their effects on the properties of bituminous mix were studied by Oluwasola et al. 2014, 2015 . The copper tailings were used at 20 content as a fine granite replacement for fraction size smaller than 1.18 mm.

Waste Mine Tailings Characterisation

This is especially true of the copper, iron, and uranium industries. A total of 31,191 million tons of overburden, waste rock, and tailings was generated by the metalore and nonmetal mineral mining industries during the period 19601977. Of this total, approximately 40 percent was generated by the copper mining industry alone.
