Best Practices for Tailings Dam Design - KCB

Background. Recent major tailings dam failures have led to an industry-wide review of the design and management of tailings storage facilities. Before the 1960s, mine tailings were often disposed directly into ponds, lakes, rivers or natural topographic depressions, or stored in impoundments supported by earthen dams, without necessarily applying engineering principles (McLeod et al. 2015).

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 extra ...
