Waste
Our mining operations produce large quantities of mineral waste such as waste rock, tailings and slag. Generally, this mineral waste is managed on-site in disposal facilities designed and operated to well-established engineering standards. We produced a total of 190 million tonnes of mineral waste during the reporting period.
Non-mineral waste is categorised as either hazardous or non-hazardous. Hazardous non-mineral waste includes oil, materials contaminated with hydrocarbons, chemical waste and spent pot linings. These hazardous wastes are recycled or disposed of in approved facilities. This reporting period we produced 51,000 tonnes of hazardous non-mineral waste that was disposed of to landfill.
