Mine tailings: reprocess recover and recycle – The Intelligent Miner

And now we’re back to metals recovery. I’m going to use a theoretical example here. Say a copper mine produced 1Mt of metal in 1999 at 90% recovery. The remaining 10% of copper around 111kt went to tailings. If the average copper price in 1999 was US$1500/tonne then that 10% represented US$166.5 million of metal.
