  • The quiet clean mining revolution

    Few industries have got the black eye, literally and metaphorically, of mining. After centuries of environmental effects ranging from toxic emissions to unsightly tailings ponds, acid mine drainage, massive energy consumption and other impacts, mining is slowly cleaning up its act. Why? Mostly because new clean technologies are increasing industrial efficiencies. They're lowering mining ...

  • Mining by-products reduce Algal Blooms

    A joint research project conducted by the Australian Commonwealth Scientific and Industrial Research Organisation (CSIRO) and the Western Australian Department of Water has shown that some mining by-products can be effective in preventing nutrients from entering river systems, thereby reducing the potential for algal blooms.A range of mining industry by-product materials was investigated to ...

  • Making green mining less of an oxymoron

    New breakthrough science and cost reductions from the world of cleantech hold promise for making mining-one of the dirtiest, most inefficient industries in the world-more profitable, safer and cleaner. But which cleantech innovations aimed at reducing toxicity in mining, as well as the need for power and water, are best positioned to succeed? Which companies will win and which will lose? How can ...

  • GRP Pipes Reign Supreme in Mine Dewatering Applications

    Glass-reinforced plastic (GRP) pipes’ proven resilience in harsh terrains, extreme climates and unpredictable site environments make them the superior choice over HDPE, steel and DICL (ductile iron concrete lined) pipes in the demanding environment of a mine dewatering system. Says Roger Rusch, CEO of IWC “Unchecked groundwater can affect the stability of the ...

  • Using mining by-products to reduce algal blooms

    A joint project between CSIRO and the Western Australian Department of Water investigated a range of mining industry by-product materials, which are currently unused, to determine whether they could instead be used to filter nutrients from natural waters or to treat wastewater that would otherwise be discarded. CSIRO project leader, Dr Grant Douglas, says the use of abundant, low-cost by-product ...

  • Dumping mine waste into Lakes - Is this the best environmental option?

    Sixteen Canadian lakes are slated to be officially but quietly "reclassified" as toxic dump sites for mines. Under the Fisheries Act, it’s illegal to put harmful substances into fish-bearing waters. But, under a little-known subsection known as Schedule Two of the mining effluent regulations, federal bureaucrats can redefine lakes as "tailings impoundment areas." Public opposition has been ...
