Mine tailings: reprocess, recover & recycle - The Intelligent Miner

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.
