  • 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 ...

  • Methods for the control of oil vapour emissions

    There are many oil vapours to discharge from oil containers into the atmosphere in oil operations (such as storage and loading). Two basic concepts are discussed regarding the control of oil vapour emission (OVE). The first is to invent active methods to restrain the OVE. The second is to develop passive tail–end remediation technologies to control the released vapour. Oil vapour recovery ...

  • Dam security and underwater attacks

    According to DHS (2007) dams provide a wide range of important economic, environmental, and social benefits. These benefits include: recreation, flood control, water storage, irrigation, mine tailings, electric generation, debris control, and navigation (see Figure 1; DHS 2007). Their destruction through intentional attack can largely impact the economy and public safety.  Dam security is ...

  • Oil and Water Don’t Mix – But Can They Co-Exist? - A GLOBE-Net Editorial

    Real progress is being made to reduce the environmental impacts of oil sands activities. But that message is being lost in the flood of bad press about contamination of adjacent waterways and the concerns about those ugly tailings ponds. Oil and water do not mix. But can they co-exist? GLOBE-Net, September 1, 2010 - August has not been a good month for the Alberta oil sands industry. The tidal ...

  • Why perform 3D slope stability analysis

    Background The benefits associated with performing 3D slope stability analyses were expounded by Dr. Del Fredlund in the 1970s.  Over the years a number of 3D methods of analysis have been researched. These methods have ranged from the method of columns to approaches based on variational calculus, and more recently, the use of dynamic programming. The interest in 3D slope stability analysis ...

  • Cyanide Spill at Baia Mare - Assessment Mission Report UNEP/OCHA

    Introduction On 30 January 2000, following a breach in the tailing dam of the Aurul SA Baia Mare Company, a major spill of cyanide-rich tailings waste was released into the river system near Baia Mare in north west Romania. The contaminant travelled via tributaries into the river Somes, Tisza and finally into the Danube before reaching the Black Sea. A team of international ...

  • Properties and Behavior of Radionuclides

    For the purposes of this document, radionuclides should be considered to have properties similar to those of other heavy metals.This does not imply that all radionuclides are heavy metals, but that the majority of sites requiring remediation of radioactively contaminated materials are contaminated with radionuclides that have similar properties. Like metals, the contaminants of concern are ...
