What emerging technologies and innovations present opportunities for economic repurposing of mined land, assets, and waste materials?

Abstract

The definition of the future use of mined lands should be considered early in the life cycle of a mine. Well-established concepts, such as “Begin with the end in mind” or “Design for closure,” have at their core the idea of having in mind the intended use of the mined area before the cessation of operational activities. However, closure is complex and the optimal future use of a mined area involves evaluation of environmental, social, and economic aspects, all of which change through the life of a mine. Closure is also a dynamic and iterative process that needs to be integrated into operations, while accounting for the possibility of temporary or sudden closure (ICMM, 2019).
