Predicting Flotation Recovery

If copper tailing is constant, and it very nearly is for a strictly sulfide copper ore, percent recovery must fluctuate almost directly to the feed assay. The accuracy of a recovery figure is first of all dependent on the accuracy of sampling and assaying. Sampling and assaying errors can become quite significant in the case of low grade ores.

Mine tailings: reprocess, recover & recycle

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$1,500/tonne then that 10% represented US$166.5 million of metal.
