Disposal ponds and tailing dams

As a consequence of the recent environmental disaster at Kolontár, Hungary, in which a red mud disposal pond collapsed, we invited two experts, Professor Karl E. Lorber and Professor Helmut Antrekowitsch of the University of Leoben, to write a guest editorial covering this topic. This guest editorial acknowledges the relevance of mining wastes in terms of quantity as well as hazard potential, and demonstrates the importance of implementing ‘best available technology’ (BAT) and environmentally sound management of mining waste.
