Mining and Minerals Solutions

  • Acid Mine Drainage

    WesTech’s acid mine drainage treatment reduces the environmental impact of acidic water generated from both operating and abandoned mine sites.
  • Coal Mining & Preparation

    Our coal mine water treatment solutions facilitate the process of coal preparation, providing commercial benefits for marginal coal supplies.
  • Man Camp

    WesTech provides potable water and sanitation systems that are easy to transport and install at remote water treatment sites for mining, oil and gas, or construction.
  • Mineral Processing

    Mineral extraction wastewater can be environmentally harmful. WesTech solutions render the byproducts inert, then reliably contain them for environmental safety.
  • Paste Thickening & Backfill

    Paste backfill is an eco-friendly material that can be used to fill cavities leftover from underground mining while disposing of sludge or mine tailings.
  • Precious Metals - Gold & Silver

    Our solutions maximize gold and silver recovery through the Merrill-Crowe process using inter-stage mixing and state-of-the-art sedimentation.
  • Tailings

    Paste, or thickened tailings, allows mines to address the environmental concerns of waste disposal while improving water recovery and dam safety.
