The viability of using gold mine tailings as a substitute for fine aggregate in concrete mixes
… for building materials, some of which requires mined natural resources. These materials produce large volumes of mining wastes (also known as tailings) which have environmental and economic implications. This research investigates the potential of recycling gold mine tailings from the …

Bioprospecting of plants species with potential to uptake inorganic chemical species from gold mine tailings and acid mine drainage
In South Africa, mining of gold and coal has huge negative impacts on the environment. This is due to the exposure of sulphide-bearing minerals such as pyrite (FeS2) to oxygenated water during and after the extraction of ore deposits which results in the formation of acid mine drainage (AMD). Acid …

Development of a computer-based advisory system for a selection of appropriate rehabilitation strategies for designated abandoned mine sites in Limpopo Province of South Africa
South Africa has many abandoned mines which seriously affect the environment and the livelihood of the host communities. The lack of in-depth knowledge of the problems of these mines, limited resources for their rehabilitation, lack of clearly assigned responsibilities for rehabilitation, and the …

The impacts and conflicts associated with defunct gold tailings storage facilities in South Africa: A case study of Davidsonville, Central Rand
Gold mining generates large quantities of tailings waste. These tailings can have a significant negative impact on the surrounding environment, with concomitant effects on local ecosystems, as well as on human health and quality of livelihoods. The latter is a concern in the Witwatersrand …

Repurposing of mine waste: an alternative management approach to gold tailings in South Africa
The large volumes of waste generated during gold beneficiation are a major pollution concern in South Africa. To remove these potential pollution risks in perpetuity, non-conventional approaches to mine waste management are required which avoid land disposal of “unwanted” material. This …

In-situ measurements and calculation of radon gas concentration and exhalation from a tailings mine dump
… underground, milled and processed to extract gold. Uranium is one of the minerals which is mined as a by-product of gold. The uranium bearing tailings are then placed on large dumps which are usually one or more kilometres in diameter in the environment. There are approximately 250 gold mine …

Hydrogeochemical Evaluation and Impact of Remediation Design on Arsenic Mobility at Historical Gold Mine Sites
Historical gold mine tailings at several sites in Nova Scotia, Canada are publicly accessible and may pose a threat to human and ecosystem health because of high arsenic (As) concentrations in the tailings (max 25 wt.%) and associated pore waters (up to 100 mg/L). Two of these sites, Montague and …
