Pipeline treatment of a copper-zinc waste stream: a pilot-scale evaluation.
Pittsburgh, PA: U.S. Department of the Interior, Bureau of Mines, RI 9589, 1995 Jan; :1-23
The In-Line System (ILS) replaces the basins, mechanical mixers, and aerators normally used in the chemical neutralization process with a jet pump and static mixer. The purpose of this study was to determine if the application of the ILS could be extended from CMD treatment to MMD treatment. The study consisted of a series of pilot-scale treatments of an MMD from a copper and zinc mine. The principal metals at high concentrations in the untreated MMD were copper, zinc, iron, manganese, aluminum, and cadium. Three neutralizing reagent was evaluated at four treatment pH values. A fourth neutralizing reagent was evaluated at one treatment pH.
