“…Other approaches, such as ion flotation, suggest good recovery for Cu (Jafari et al 2017). Acid mine drainage (AMD) remediation has high costs, but could represent a source of metals, as shown by Skoronski et al (2017), through recovery of Al and Fe contaminants in usable forms, and show new forms to minimize the cost of water treatment (Akinwekomi et al 2020, Ryan et al 2017). The work of Antunes et al (2010);Hedin (2003); Silva et al (2019); and Valente et al (2016) indicate the potential of recovering ochre-precipitates from passive AMD treatment, for use as pigments and in the ceramic sector.…”

We characterized the tailings from the Santa Barbara tailings dam, which is located in Minas Gerais, southeastern Brazil, to: (i) identify its chemical, mineralogical, and metallurgical properties, and (ii) perform an environmental evaluation of the water at the surface of the tailings facility. The potential recovery of elements such as Sb, As, and Au was also considered for potential tailings reuse. The water was alkaline, with maximum pH values of ≈ 10, and contained potentially toxic elements, such as Sb (up to 0.500 mg/L), As (up to 0.080 mg/L), and Cu (up to 20 mg/L). Gold enrichment areas were found in the tailings dam, with concentrations up to 0.5 g/t. Alignment exists among tailings management, demand for critical raw materials, and increased interest in the processing of low-grade ores and mining waste, which is important in the context of the circular economy. They suggest that valorisation of tailings, although challenging, can be achieved by economic recovery of the more valuable metals.

“…The adsorptive capacity of acicular goethite nanoparticles (AGNs), obtained from the active AMD treatment on an industrial scale, was evaluated for the removal of arsenate, phosphate and humic acids in aqueous solution(Moreira et al, 2017). The adsorption performance of the AGNs produced from AMD was similar to the synthetic iron oxides.Acidic coal mine drainage was used as an extraction solution to dissolve aluminum from water treatment residuals and to recovery Al as coagulant(Skoronski et al, 2017). The recovered coagulant performed well in water treatment tests.scale particles (dNP) on contaminant dynamics in a coal mine AMD treatment system.…”

The recent research and development on mine drainage published in 2017 was summarized in this review. In particular, this review was focused on three main aspects: 1) mine drainage and its environmental impact, 2) prediction and prevention, and 3) treatment technologies. The first section covers physiochemical characterization, microbiological characterization, and environmental impacts. The second section includes mine drainage prediction and prevention. The final section focuses physiochemical treatment, biological treatment, passive treatment, and beneficial uses of mine drainage and treatment wastes.
