Managing waste from mining and smelting

The discharges from mining and smelting industries are typically in the form of liquid effluent, solid waste and air emissions. Regulating and enforcing how these kinds of waste discharges are managed will help to protect the environment and human health.

In addition to regulating the mining sector, there are responsibilities for regulating/authorizing the quantity and quality of any discharge of waste to the environment from activities relating to mining and the exploration of:

  • Metals
  • Non-metals
  • Coal
  • Gemstones
  • Industrial mineral ores (such as diamonds)
  • Beneficiating mineral ores (e.g. custom milling)
