  Recovery of strategically important critical minerals from mine tailings

  202261 · The processed tailings, which become less harmful to the environment, can be used as backfills for open pits and underground mines [24], [25], building materials and agriculture fertilizer (Hu et al., 2017). Repurposing tailings these ways have the potential for both economic and socio-environmental benefits (Vitti & Arnold, [26] ).

  Stirred-tank bioleaching of copper and cobalt from mine tailings …

  202241 · Abstract Metals from low-grade sulfide ores, electronic waste and mine tailings can be recovered using biohydrometallurgy. In this study, acidophilic microbial consortia of mesophiles and moderate thermophiles were applied in shake flasks as well as in stirred tank reactors (STR) to bioleach cobalt and copper from mine tailings in Chile.

  Socio-Environmental Risks Linked with Mine …

  2023821 · Abstract Soil remediation with minimum amendments is a good strategy for tailings disposal. Carbonate-rich gold-copper mine tailings occurring alongside the Yangzi River, China, were employed as the objective in this study. They showed the characteristics of fine particles and alkaline pH with high density and low nutrition.

  Phytostabilization of copper mine tailings with biosolids: Implications ...

  2008520 · Abstract A greenhouse pot experiment was conducted to evaluate the feasibility of using biosolids and Lolium perenne for the phytostabilization of copper mine tailings and to evaluate the patterns of metal accumulation and translocation in plants. Biosolids were applied either on the surface or mixed with the tailings at rates of 0, 6, and …

  Copper Tailing - an overview | ScienceDirect Topics

  The properties of copper tailings, a fine-grained residue waste produced from beneficiation of copper ore, and their effects on the properties of bituminous mix were studied by Oluwasola et al. (2014, 2015). The copper tailings were used at 20% content as a fine granite replacement for fraction size smaller than 1.18 mm.

  Modelling Hazard for Tailings Dam Failures at Copper Mines …

  The global mining industry generates several billion tons of waste every year. Much of it is stored in liquid form, known as tailings, in large impoundments. Recent dam failures at tailing ponds with catastrophic outcomes have raised public concern, such that industry initiatives and investors are beginning to address the problem. So far, a lack of publicly available …
