Waste production and disposal in mining, milling, and

The operation of uranium mining and milling plants gives rise to huge amounts of wastes from both mining and milling operations. When pyrite is present in these materials, the generation of acid drainage can take place and result in the contamination of underground and surface waters through the leaching of heavy metals and radionuclides.

Industrial Wastewater National Pollutant Discharge

Nov 12, 2020· Mining. Mining operations are often complex undertakings that may be situated in or near diverse and sensitive environments. These operations generate tailings and waste rock for disposal and also create wastewater discharges and air emissions. As a result, mining can affect surface and ground water quality, drinking water supplies and air quality.

Lecture 4: Mining waste SGU

Mining produces large amounts of waste. In Sweden, the mining industry accounts for over 80 percent of the country’s total waste production each year. While the amount of waste can be substantial, not all waste is considered harmful to the environment. Some waste might even be safe to use in other applications, such as in building materials.
