lead and mercury emissions from mining. global releases of lead from smelting and refining nonferrous metals total over 28,000 metric tonsyear. global releases of mercury from smelting and refining nonferrous metals total 710 metric tonsyear brilliant earth uses recycled gold to help reduce destructive practices associated with gold mining. To limit the environmental damage, mines often construct dams and place the toxic waste inside. but these dams do not necessarily prevent contamination of the surrounding environment. toxic waste can easily seep into soil and groundwater, or be may 16, 2018 management risks in mining management risk affects every company, but mining stocks are particularly prone to executive trouble.
