Dense-sludge process for reduced AMD sludge disposal

Mining Engineering, 1999, Vol. 51, No. 11, pp. 26-30
Zick, R.L.; Leon, M.H.; Finn, D.C.


ABSTRACT:
The high-density sludge process was originally developed by Bethlehem Steel Corp. for use on acid mine drainage (AMD) and diluted waste pickle liquor discharges requiring continuous chemical-treatment. This work began in the early 1970s and was first put into practical use around 1973. To date, there are approximately 15 operating systems that have been installed to treat mine drainage in the United States. In addition, there are another 10 systems installed outside of the United States.
