  • Potash slope stability using SVSlope

    A project recently undertaken by students at University of Regina involved slope stability numerical modeling of potash tailings. The work involved two primary objectives: Use slope stability software to determine the factor of safety of one side of the waste pile, and Perform a sensitivity analysis to identify the safe terminal height and optimized volume that could fit within the current land ...

  • Evaluation of atmospheric particle dispersion at a contaminated mine using biomonitors

    This study has carried out the assessment of magnitude of toxic elements contamination in and around the Sao Domingos mining area, a copper-sulphide open pit mine, and atmospheric transport of above elements by using lichens and Instrumental Neutron Activation Analysis (INAA). Samples of the epiphytic lichen Evernia prunastri and soils were collected. The concentrations of As, Sb, Fe and Zn were ...

  • Case study: Mechano-chemical grinding

    Challenge Traditional grinding mills reclaim only a fraction of precious metals from ore, leaving valuable material in the tailings. These minerals are more difficult to liberate, as it requires the ore to be ground to a very fine mesh. Approach GK was approached by a company who had a proprietary chemistry solution for recovering minerals from an existing ...

  • Landfill Cap Enhancements

    Introduction: The precipitation to the landfill cover is balanced by the combination of following effects: run-off, cumulating in soil, evapotranspiration, and percolation. For a given amount of precipitation, in order to reduce or eliminate percolation, the effects of run-off and/or evapotranspiration need to be enhanced. Water Harvesting Water harvesting uses ...

  • It was a Great, Green Year: Identification of a Chlorophyll Dephytylase That Functions in Chlorophyll Turnover

    Green may have been the Pantone Color of the Year for 2013 (http://www.pantone.com/color-of-the-year- 2013), but 2016 was a great year for papers on chlorophyll research, at The Plant Cell and beyond. In this year, we saw a pile of interesting papers examining chlorophyll degradation, including its regulatory mechanisms. For example, to identify transcription ...

  • Forgotten asbestos mine sickens Indian villagers

    Asbestos waste spills in a gray gash down the flank of a lush green hill above tribal villages that are home to thousands in eastern India. Three decades after the mines were abandoned, nothing has been done to remove the enormous, hazardous piles of broken rocks and powdery dust left behind. In Roro Village and nearby settlements, people who never worked in the mines are dying of lung disease. ...
