Closure options under consideration at some sites include backfilling mined-out pits with waste rock. Backfill may include mineralised and non-mineralised waste rock. Following groundwater rebound, flow-through conditions may develop in the pit post- closure. The backfill located in the Read more... about Backfilled Pits – Laboratory-scale Tests for Assessing Impacts on Groundwater Quality

During active mining and post closure, the control of water requires prudent site management to firstly minimise the generation of minewater and secondly to treat where necessary. In order to reduce associated treatment costs in the long term, artificial wetlands have gained acceptance, Read more... about Passive Treatment: A Walk Away Solution?
