Mining, the environment and the treatment of mine effluents

The environmental impact of mining on the ecosystem, including land, water and air, has become an unavoidable reality. Guidelines and regulations have been promulgated to protect the environment throughout mining activities from start-up to site decommissioning, in particular, the occurrence of acid mine drainage (AMD), due to oxidation of sulfide mineral wastes, has become the major area of ...

VSEP filters mine tailing pond effluent with no pre-treatment required

New Logic International installed its Vibratory Shear Enhanced Processing (VSEP) system in March, 1998 at a major California rare earth mining and manufacturing facility. The VSEP is used for treatment of mine tailing pond effluent at this facility with no pretreatment required. The VSEP system uses nanofiltration followed by ultrafiltration membrane modules and is able to treat the mine tailing ...

The recovery of copper from a copper mine effluent in a hybrid flotation/microfiltration cell

A new hybrid process for cleaning wastewater, combining flotation and membrane microfiltration, was investigated. The hybrid process combined the advantages of both flotation and membrane separation: the flotation cell removed a large proportion of suspended solid particles, while the membrane module produced clean water permeate effluent. The hybrid cell performance has been studied in depth and ...

Root length of aquatic plant, Lemna minor L., as an optimal toxicity endpoint for bio‐monitoring of mining effluents

Lemna minor, a free‐floating macrophyte, is used for bio‐monitoring of mine effluent quality under the Metal Mining Effluent Regulations (MMER) of the Environmental Effects Monitoring (EEM) program in Canada, and is known to be sensitive to trace metals commonly discharged in mine effluents such as nickel. Environment Canada's standard toxicity testing protocol recommends frond count (FC) and ...

Relationships between sources of acid mine drainage and the hydrochemistry of acid effluents during rainy season in the Iberian Pyrite Belt

In the Iberian Pyrite Belt (IPB), southwest Spain, a prolonged and intense mining activity of more than 4,500 years has resulted in almost a hundred mines scattered through the region. After years of inactivity, these mines are still causing high levels of hydrochemical degradation in the fluvial network. This situation represents a unique scenario in the world, taking into consideration its ...

Biodepuration of domestic sewage, textile effluents and acid mine drainage using starch-based xerogel from recycled potato peels

Water is a finite resource. Its safety and cleanliness are highly important to meet current and future human needs. Compared to other resources, water represents a main factor to achieve development in several areas and leads to economic progress of a nation. However, in recent years, the excessive demographic and industrial growth has exacerbated water contamination. In this study, the ...

Assessment of nanofiltration and reverse osmosis potentialities to recover metals, sulfuric acid, and recycled water from acid gold mining effluent

This work assessed the potential of nanofiltration (NF) and reverse osmosis (RO) to treat acid streams contaminated with metals, such as effluent from the pressure oxidation process (POX) used in refractory gold ore processing. NF and RO were evaluated in terms of rejections of sulfuric acid and metals. Regarding NF, high sulfuric acid permeation (∼100%), was observed, while metals were ...

Wastewater Treatment for the Mining Industry

Sustainable wastewater technologies minimize mining’s environmental footprint Mining for some minerals, including coal, has been diminishing due to increased financial, social, and environmental pressures, both in the United States and abroad. At the same time, mining for lithium and other metals — used in energy storage for electric cars, and wind and solar generation — is ...

Dissolved radionuclide in the industrial effluent of uranium facilities, Jaduguda, India

Dissolved radionuclides in the effluent of uranium mining industry were studied. Activity concentrations of uranium and radium were estimated in effluent water from different uranium mines and mill tailings ponds. The concentrations of U and 226Ra in untreated effluent water were found to be elevated. The concentrations of dissolved radionuclides in the adjacent aquatic ...
