Beneficiation of acid mine drainage (AMD): A viable option ...

15/03/2020  Pollution of water resources by acid mine drainage (AMD) has been an issue of primary concern in recent decades. This is rooted to the fact that AMD negatively affects the environment and its suitability to foster life. As such, efforts to recover, valorise and beneficiate minerals acquired from AMD treatment process have been ongoing, albeit with minimal success. With that in mind, this study unpacks novel ways of beneficiating AMD

acid mine drainage (AMD) has been a worrisome issue of concern to national, regional, and international scientific communities alike. This is attributed to the magnitude of toxicological effects to living organisms upon exposure to AMD. Specifically, AMD grossly results from various geogenic and anthropogenic activities that lead to the generation of metalliferous and acidic drainage. In most ...

Acid mine drainage - Wikipedia

Acid mine drainage also affects the wildlife living within the affected body of water. Aquatic macroinvertebrates living in streams or parts of streams affected by acid mine drainage show fewer individuals, less diversity, and lower biomass. Many species of fish also cannot tolerate the pollution.

feed material. In the case of Acid Mine Drainage, up to 97% of the water can be filtered in a single pass filtration using V SEP. Flux is inversely related to % recovery, so the optimum % recovery may vary for each application. Other methods like filter presses are done in batch mode with operators opening and cleaning the filter cake on a regular basis. V SEP is a continuous

Of most concern and increasing interest is the prevention and control of acid mine drainage (AMD) and its treatment. Acid mine drainage has the potential to impact negatively on aquatic ecosystems and groundwater availability in particular. Acid mine drainage (AMD) is generally regarded as the principal environmental problem caused by the mining of the sulfide ore deposits. In coal combustion in power

Treatment of Acid Mine Drainage

A. What is Acid Mine Drainage? Acid mine drainage is a natural consequence of mining activity where the excavation of mineral deposits (metal bearing or coal), below the natural groundwater level, exposes sulphur containing compounds to oxygen and water. Since the introduction of steam powered engines it has been possible to mine ores substantially below the groundwater level. There is also a problem

Acid mine drainage - Wikipedia

By far, the most commonly used commercial process for treating acid mine drainage is lime precipitation in a high-density sludge (HDS) process. In this application, a slurry of lime is dispersed into a tank containing acid mine drainage and recycled sludge to increase water pH to about 9. At this pH, most toxic metals become insoluble and precipitate, aided by the presence of recycled sludge. Optionally, air

Acid Mine Drainage - Earthworks

Acid mine drainage can be released anywhere on the mine where sulfides are exposed to air and water — including waste rock piles, tailings, open pits, underground tunnels, and leach pads. Acid drainage is often marked by “yellow boy,” an orange-yellow substance (visible in the photo on this page) that occurs when the pH of acidic mine-influenced water raises above pH 3 (approaching more ...

Case Study Acid Mine Drainage South Africa - Earthwise

Acid mine drainage is a severe example of polluted groundwater, but as this case study shows, groundwater and surface water are linked and both can affect the other. By 2009 there were reports that the one remaining mine at Grootvlei, in the more populated Eastern basin, was in financial difficulty. If the mine stopped operating and dewatering stopped, there was a risk of acid mine drainage ...
