Development of ECO-UHPC utilizing gold mine tailings as quartz sand alternative

open access: yesCleaner Engineering and Technology, 2021
To ensure ultra-high performance, in terms strength and durability, coarse aggregate is typically avoided in UHPC (ultra-high performance concrete). Instead, very fine quartz sand is usually used as the only aggregate.

Potential Impacts of Tailings and Tailings Cover Fertilization on Arsenic Mobility in Surface and Ground Waters [PDF]

open access: yes, 2008
A number of mining sites worldwide, particularly gold mines, have tailings management facilities (TMFs) that contain high levels of arsenic. Current closed mine site regulatory agencies tend to prefer revegetation of TMFs as part of the mandated ...

Growth of soil algae and cyanobacteria on gold mine tailings material

open access: yesSouth African Journal of Science, 2017
The goal of revegetation of gold mine tailings storage facilities is to reduce aeolian pollution, nutrient leaching and erosion caused by exposure to wind and water. The establishment of biological soil crusts may prove to be a more cost-effective way to

Semiarid bunchgrasses accumulate molybdenum on alkaline copper mine tailings: assessing phytostabilization in the greenhouse

open access: yesSN Applied Sciences, 2021
Article Highlights Compost increased P. spicata and F. campestris root and shoot biomass on alkaline copper mine tailings. Ash increased tailings pH and bunchgrass shoot uptake of molybdenum. P. spicata and F.

Biochar, compost and/or NPK fertilizer affect the uptake of potentially toxic elements and promote the yield of lettuce grown in an abandoned gold mine tailing

open access: yesJournal of Trace Elements and Minerals, 2023
Background and study objectives: The low soil quality status and the high concentrations of potentially toxic elements (PTEs) found in gold mine tailings make them unfit for crop production.

Jarosite versus Soluble Iron-Sulfate Formation and Their Role in Acid Mine Drainage Formation at the Pan de Azúcar Mine Tailings (Zn-Pb-Ag), NW Argentina [PDF]

open access: yes, 2014
Secondary jarosite and water-soluble iron-sulfate minerals control the composition of acid mine waters formed by the oxidation of sulfide in tailings impoundments at the (Zn-Pb-Ag) Pan de Azúcar mine located in the Pozuelos Lagoon Basin (semi-arid ...

Environmental hazard assessment of a marine mine tailings deposit site and potential implications for deep-sea mining [PDF]

open access: yes, 2017
Portmán Bay is a heavily contaminated area resulting from decades of metal mine tailings disposal, and is considered a suitable shallow-water analogue to investigate the potential ecotoxicological impact of deep-sea mining.
