Chapter 8 Environmental Aspects of Copper Production

Copper Production Copper production is not an environmentally benign activity. From mining and milling through hydro- and pyrometallurgical processing to refin-ing, copper production can have significant ad-verse impacts on air quality, surface and ground-water quality, and the land (see figure 8-1 ). While these impacts can be severe when the

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.
