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 materials
Green Valley, Arizona is a retirement community located near major open-pit copper mines. Mining and milling activities create dust, which degrades air quality, and mine dumps and tailings banks, which degrade the viewscape. Although the tailings banks are highly visible, this study found that consumer surplus lost from dust-polluted air is more than twice that from degradation of viewscape ...
