Copper Tailing an overview ScienceDirect Topics

The properties of copper tailings, a fine-grained 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

Sep 13, 2019· The remaining 10% of copper, around 111kt, went to tailings. If the average copper price in 1999 was US$1,500/tonne then that 10% represented US$166.5 million of metal. Fast forward 20 years and at today’s price, US$5,842/tonne,if that material could be reprocessed and an extra 2.5% of copper recovered (or more), then that’s an additional US$162 million+ of revenue.
