8.2: Mining and Ore Processing
Some of the potential environmental effects of metal mines are summarized on Table 8.2. All mining activities result in a loss of natural environment because land has to be cleared and is no longer available for or useful to the plants and animals that once lived there. Mining involves blasting, breaking and crushing rock, and so dust is created.
