· 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. Fast forward 20 years and at today’s price, US$5,842/tonne, if that material could be reprocessed and an

The TSF at Ballarat Gold Mine is a compacted clay lined dam to prevent tailings and water from escaping into the groundwater. The nature of TSF design and operation is fundamentally different from a water collection dam. TSF’s are designed not to collect runoff and to remain as dry as possible. TSF’s are not intended for the storage of water.

· Tailings Recycling Methods. Porphyry copper deposits are commercially viable if they have a grade of 0.4% (Park et al. 2019). This ore grade would result in 99.6% of the source material going to waste as slag and tailings. Tailings ponds contain minerals that react in aerobic and aqueous conditions, such as iron and arsenic-baring sulfide
