Evaluation of geological CO 2 storage involving adsorption on mining wastes from coal processing
… their applicability for CO2 storage. In mining regions world-wide, ground subsidence originating from extensive mining is a serious problem resulting in damage which greatly increases the costs of raw material production. Within the scope of this thesis an approach for sorptive CO2 …

The impact of nonpoint source pollution from mining wastes on water quality, Elko County, Nevada
… impacts commonly associated with mine wastes, such as acidification and increases in suspended sediment concentrations were not found to be occurring at the site, due to factors such as carbonate buffering of acidity and the presence of sediment control structures at the site.

A Survey of Pollution on Selected Streams in the Black Hills of South Dakota
… both sewage treatment plant effluents and mining wastes. A comparison of the benthic fauna community below a pollution source to that above it was the primary basis for evaluating the effect of the pollution source on the stream. The results of the benthic fauna samples indicated that the …

Contaminant reduction by iron oxide nanoparticles: Environmental variables and evolving reactivity
… from drinking water resources, treatment of mining wastes, and remediation of groundwater contaminated by industrial activity. There is still much to be understood, however, about the reactivity of iron oxide nanoparticles in actual groundwater systems, where mineralogy and solution …

An investigation into accelerated leaching for the purpose of ARD mitigation
… environments with current or previously active mining activities. Formed from the exposure of sulphide mineral to both water and air, and catalyzed by naturally occurring iron- and sulphur-oxidizing micro-organisms, ARD pollution is predominantly associated with the mining of sulphidic ores and …

The viability of using gold mine tailings as a substitute for fine aggregate in concrete mixes
… 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 Witwatersrand region as a substitute for fine aggregates in concrete. …

First update of the regional database of storage facilities (mining and mining-metallurgical waste deposits) in Sardinia
… inventory and geospatial database of mining and metallurgical waste deposits in Sardinia (Italy), developed within an ISPRA–UniCa project funded by the Italian PNRR. The study addresses the growing interest in mining waste as a potential secondary source of Critical Raw Materials …

Development of ultrasensitive electrochemical sensors based on nanocomposites for environmental applications
… problem generated from industrial effluents, mining wastes, or domestic sewage, and the widespread use of pesticides in pest control in the environment. In the last years, heavy metals have risen significantly, especially in the developed country where most pollutants are used. According to …

Desulphurisation flotation for the selective removal of pyrite from coal discards using microorganisms
… processes such as base metal and coal mining produce large amounts of waste rock and coal discards that contain significant quantities of sulphide minerals with Acid Rock Drainage (ARD) generating potential. ARD is caused by the exposure of sulphide minerals, primarily pyrite (FeS2), to …
