Managing the waste rock storage design — can we build a waste rock dump that works? [PDF]
Proceedings of the International Conference on Mine Closure, 2016 For a waste rock dump to be managed both during operations and at closure, a thorough understanding of the composition of the waste is an important requirement. A comprehensive block model should be prepared, with an appropriate materials management and placement plan developed in conjunction with the mining schedule.

Localized Sulfide Oxidation Limited by Oxygen Supply in a Full-Scale Waste-Rock Pile
Vadose Zone Journal, 2018 Open-pit mines produce large amounts of waste rock that is placed on-site, often in tall, mixed-composition piles. These waste-rock piles pose environmental risks because their weathering (i.e., sulfide oxidation) may generate acidic and metal-laden ...
