Improving Mine Waste Management

Waste is a huge challenge in the mining industry, with waste rock and tailings containing hazardous substances that have detrimental effects on the environment, causing air pollution and water contamination.

Mining waste management must include both short-term and long-term environmental monitoring strategies if the industry is to support a sustainable future.

Key fact: In Sweden, the mining industry accounts for over 80% of total waste production each year

The hazards of mine tailings can be mitigated through dry stacking. Traditionally, tailings ponds are used to store this hazardous waste, but these can fail due to erosion, seepage, and overtopping. Dry stacking is more sustainable because tailings are dewatered and compacted into a mound, and the surrounding area can be reclaimed.

Mine waste can also trap excess CO2. This process, called carbon mineralisation, already happens in mine tailings, but can be accelerated by reprocessing technologies to offset GHG emissions.

Automation is also key to minimising waste while maximising production and reducing emissions. Automated equipment performs more accurately and efficiently, and can be combined with AI technology to identify areas of optimisation in terms of waste management and energy consumption.

Benefits

  • Reduces GHG emissions

  • Mitigates impact of environment

  • Future-proofs mining operations
