Case study - tailing ponds
Location: Canada Year: 2012 Working context Oil Sand - Tailing pond dredging - The standard industry practice is to pump oil sands tailings into large settling ponds. There, the heaviest material settles to the bottom, separating from the top layer of water which can be recycled. The problem Oil sands tailings are a mixture of water, clay, sand and residual hydrocarbons produced during the ...

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 ...

Tailings Pond Geomembrane Construction Plan and Construction Precautions
The development of the mining industry brings not only a large amount of ore but also many tailings problems to be solved. Yet, tailings stored in tailings ponds often contain a large number of metals, heavy metals, and mineral processing residues. Once environmental pollution occurs, the consequences will be very serious. Thus, anti-seepage measures are usually taken for tailings ponds. The ...

Investigation of contaminant transport in groundwater from the tailings pond of uranium mine: a case study
The present study investigates the spreading of radioactive materials through groundwater by developing a groundwater contaminant transport model. The model was analysed in the steady state, and was then applied in the transient state to predict the spreading of uranium and its daughter product in the region. The model was verified using the simulated and measured velocity of groundwater. It was ...

French Drain Monitoring at Toe of Tailings Dam - Case Study
SSR Mining needed to monitor the temperature profile along their French Drain system each winter. Freeze of the drain could result in seepage from the tailings pond into the adjacent lake. beadedstream’s solution allowed them to collect high quality data to monitor the performance of the drain and to mitigate any freezing that ...

Geochemical modelling of the evolution and fate of metal pollutants arising from an abandoned gold mine tailings facility in Johannesburg
Analytical techniques were combined with geochemical modelling to study the release mechanisms of pollutants from an abandoned gold mining tailings storage facility near Johannesburg. Inverse modelling of sampled tailings pond water and experimental single extractions using various solutions indicated which combination of naturally occurring leaching solutions were likely to give rise to the ...

Dr Abe Beagles White Paper on Galamsey Mining in Ghana
Dr Abe Beagles White Paper on Reclaiming Galamsey Mined Lands in Ghana, has come about because of the devistation that has occured in Ghana in West Africa and all over the areas that have been mined by unknowing or uncaring companies and individuals who came to West Africa for the vast riches in Gold and other minerals over the past 13 to 15 years. However, in 2011 the government stopped all ...

Cut-Off Wall - Abandoned Mine Tailings Pond - Case Study
Problem At an abandoned mine in the Yukon Territory, mining for both Gold and Zinc took place until the mid 1950's, with the processing of the ore taking place on the banks of an adjacent lake. Processing methods resulted in the creation of a large mine tailings pond that had high concentrations of iron, arsenic, zinc and lead. Spring runoff and summer rainfall then infiltrated through the pond ...

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 streams and river were ...

Radiological safety and environmental monitoring aspects of mining and processing of uranium ore at Jaduguda, India
Low–grade uranium ore is mined and processed in India since the early 1970s. To adhere to the regulatory compliance monitoring of external gamma level, radon and long–lived alpha activity of ore dust is carried out in uranium mines. Apart from this, surface contamination is also monitored in radiologically important areas of ore processing plant. Exposure of occupational workers is evaluated ...

Gassy Ponds May Hold Key to Alberta`s Oil-Sands Emissions Battle
(Bloomberg) — Alberta's battle to reduce oil sands' greenhouse gas emissions is taking aim at one of the industry's biggest environmental bugaboos: tailings ponds. While producers have focused on curbing methane from drilling operations, the ponds, designed to hold residue from mining operations, are among the largest sources of emissions for oil-sands miners, said Eric Newell, a former ...
