Mining waste are regularly cited as potential secondary resources that could give access to residual concentrations of the exploited metals and also unrecovered metals, nowadays of economic importance for new high-tech applications. This article describes the investigation of three distinct mine tailings, and discusses the opportunity of re-processing such secondary mining resources, as part of the overall mining site management.
