  • 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 ...

  • On the use of risk measures in solvency capital estimation

    Regulation on the minimum capital that a financial institution or an insurance firm must hold to guarantee its solvency is proportional to a measure of its global risk. Using Monte Carlo simulation we show that, in some instances, risk measures can substantially underestimate risk. So, we address the implications on the choice of the risk measure that determines the economic capital requirement. ...

  • 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 ...

  • 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 ...

  • Bioremediation of copper mine waste: a case study from Mosaboni copper mines, Eastern India

    The concentrations of different forms of heavy metals were determined in a mine dump rich in chalcopyrite, pyrite, pyrrhotite, molybdenite and other sulphide minerals. A pilot scale study was conducted by transporting 14 tons of copper tailings from Mosaboni mines and exposed to natural weathering conditions and normal plant colonisation for one year. After one year different forms of metals were ...

  • Wasted sales efforts (leaky funnel?)

    Sales Methodologies (Processes) Every year, it seems, there emerges some new sales philosophy or methodology. Perhaps this is part of the sales energy-renewal process: some new approach to selling, preached with the fervour of a new religion by its evangelists (consultants). Some of the popular ones include Miller Heiman, Solution Selling, Selling with Integrity, ROI Selling, PoV Selling, ...

  • Occurrence of rate limited sorption in stormwater biofiltration systems

    Batch and column studies were conducted using synthetic stormwater with mixtures of 0.6 mm glass beads and compost particles of either 1.18 or 4.75 mm. Batch tests showed that rate limited uptake of zinc occurred onto both particle sizes. The column containing the 1.18 mm particles could be fitted by a Freundlich sorption isotherm while the other column exhibited a diffuse front and tailing and ...

  • Generalized Calibration of a Nuclear Moisture/Density Depth Gauge

    The application of nuclear moisture/density depth gauges to soil deposits has generally relied on calibration by direct correlation with measured values of moisture content and density. In very soft variable deposits such as coal tailings, direct calibration is not possible. A generalized calibration can be developed from first principles based on the elemental composition of the soil being ...

  • Seasonal variation in suspended particulate matter vis-a-vis meteorological parameters at Kolar Gold Fields, India

    Particulate matter concentrations and meteorological parameters were monitored to assess the impact of other industries likely to be set up at Kolar Gold Fields, India. Particulate matter less than 10 µm was the highest in winter due to the influence of gold mill tailings dumps while total suspended particulate matter was generally higher in spring probably due to the influence of uncovered area ...

  • The investigation of arsenic and heavy metal concentrations in soil, water and crops around abandoned metal mines

    Soils, water and crops around abandoned metal mines can be contaminated by heavy metals from adjacent tailings and waste rocks accumulated during mining operations. The results indicate that the As, Zn, Cd, and Cr concentrations exceed the soil contamination standard in many soil samples of the nearby farmlands as well as the tailings sites. In the case of water quality, the As concentrations in ...
