Sources and Treatment of Wastewater in the Nonferrous

The intent was to assess the applicability of existing wastewater treatment technology to the effluents generated by the primary and secondary copper, lead, and zinc industries. A list of industries and processes they employ which discharge acidic wastewater containing metals was compiled by reviewing available literature.
