Abstract
"The primary objective of this study was to evaluate the trace organic contributions by two lead and zinc mining and milling operations in Southeastern Missouri. A secondary objective was to evaluate a reverse osmosis-solvent extraction method for use in recovering trace organics.
Trace organics were recovered in the first phase of the study following procedures as outlined by the American Society of Testing and Materials (ASTM), with chloroform and benzene being used as the solvents. The data indicated that the milling waste contained a larger concentration of trace organics than the excess mine water. Furthermore, it was shown that recycling the mill waste not only reduced the level of trace organics emitted for treatment, but also the level discharged to the receiving stream after treatment.
The second phase of the study utilized a tubular reverse osmosis unit and a simplified solvent extraction procedure. An oil leak from the high-pressure pump invalidated the results obtained on the concentrate waters. However, the low concentration of trace organics obtained from some of the product waters, with respect to the feed waters, indicated that the reverse osmosis unit may be capable of concentrating trace organics"-- Abstract, p. ii
