and beneficiation activities (including dust control), pumped to tailings impoundments, or discharged as a waste through an NPDES permit. Because mine water at copper mines is often rich in dissolved copper and other metal ions, some operations pump it to an SX/EW plant to recover the copper values (Cumming 1973).
