Mining Waste Management in Papua New Guinea is a Challenge

Challenge in the Mine Waste Management refers to difficulties experience by mining industry in managing the mine related wastes in order to effectively protect the surrounding environment.

Factors contribute to the issues in the Mining Industry include but not limited to:
  • Natural Factors
  • Waste/mine water treatment and tailings /waste discharge into river systems and Deep Sea  Tailings Placement (DSTP).
  • Disputes between landowners...
Natural factors in the tropics with  high altitude and high annual rainfall (2000-5000mm) pose threat to the stability of tailings dam construction due to potential failure.
Other factors that attracts more attention are tectonic plate movements and structures along or near the Pacific Rim of Fire.

In such circumstances, the Mining Industry discharges waste into the river systems which causes pollution to the riverine and ecology within the vicinity of the mine impacted communities downstream.

Deep See Tailings Placement is another option that the industry looks at where there is no river system that is feasible to discharge tailings.

Continuous deposition of waste and tailings into the river systems not only cause pollution but also sedimentation and turbidity issues that reflect in the river course diversion and disturb the environment.

The Mining Industry utilizes all available technologies to treat waste water at processing plant sites and raise the pH to 8-12. There are certain spots where water samples collected and tested to analyse the water quality. Mine Waste Management is always a challenge even though continuous efforts invested every second.
