Potentially Exploitable Reprocessing Routes for Recovering Copper
4/1/2021· Abstract This research aimed at recovering metals retained in the tailings from the flotation of copper (Cu) and cobalt (Co) ores conducted at the New Concentrator in Kipushi (NCK). Metals retention in the tailings (0.73% Cu and 0.37% Co) increased due to the removal of the gravity separation section from the processing circuit together with changes arising in the
Tailings Copper Mountain Mining Corporation
Copper Mountain takes tailings management seriously and prioritizes safety, transparency, and accountability. Our tailings operations achieved a “AA” rating under TSM protocols, and we are confident in our long-term reclamation plan to return the site to its natural state. Tailings are natural, finely ground rock or sand that remains after economic minerals have been removed.
Tailings re-handling and reprocessing Royal IHC
Tailings management requires a careful approach and integrated solutions. All aspects relating to de-risking, re-handling, water management and reprocessing need to be considered in a sustainable way. The focus should be on safe, efficient and effective operations to unlock the potential of these mining legacies.
Reprocessing historic tailings three Chilean case studies
Reprocessing historic tailings operations. Many old tailings were produced by less efficient technologies than those available nowadays and have grades that are comparable or higher to the current typical head grades. Moreover, as the old tailings have already undergone a size reduction process, they require little additional regrind energy to reprocess them. In some
