Aspects of Design and Operation of Heap Leach Pad and Spent Ore Dump

April 2021

Publication - Article

Heap leach pads are composed of mined ore, usually crushed, disposed on drainage system to be processed with leach solutions. In the case of dynamic heap leach, after the leaching process, spent ore is transported by conveyor belts to be disposed into dumps.

Complexities of Underground Mining Seismic Sources

Lindsay Linzer, Mark Hildyard, Johan Wesseloo - March 2021

Publication - Published Paper

A numerical investigation on the influence of the mining environment on seismic sources, with a focus on pillar failure mechanisms in tabular mining. We investigate the influence of the mining stope (underground excavation or void) on seismic inversions for the scalar moment.

In-pit Tailings Storage Facilities – Easy Win or Long-term Liability?

Sam Paterson - June 2021

Publication

An in-pit tailings facility may be a low-cost tailings option for an open cut mine; but an assessment that doesn’t capture the cost of remediating residual voids risks underestimating the actual cost to the operation.

TSF Failure – Standards for Response and Recovery

Andries Fourie, Edrie du Plessis, Jessica Edwards - July 2021

Publication - Article

Even with the range of mitigation measures applied by mines to ensure that tailings storage facilities (TSFs) are safe, the Global Industry Standards on Tailings Management (GISTM) highlights that catastrophic failure may still occur – and outlines how mines should then respond.

Social Engagement Prioritised in New Tailings Standard

Vassie Maharaj, Franciska Lake, Jessica Edwards, Matthew Law - July 2021

Publication - Article

Its probably not by chance that the first principle of the Global Industry Standard on Tailings Management (GISTM) is to “respect the rights of project-affected people” and to “meaningfully engage them at all phases of the tailings facility lifecycle”.
