Epa design manual neutralization of acid mine drainage

EPA /^ June * LIMESTONE AND LIMESTONE-LIME NEUTRALIZATION OP ACID MINE DRAINAGE By Roger C. Wilmoth Mining Pollution Control Branch Industrial Waste Treatment Research Laboratory Program Element No. 1BBC40 NATIONAL ENVIRONMENTAL RESEARCH CENTER OFFICE OF RESEARCH AND DEVELOPMENT U.S. . Acid Mine Drainage Prediction Acid mine drainage prediction tests are increasingly relied upon to assess the long-term potential of acid generation. This concern has developed because of the lag time at existing mines between waste emplacement and observation of an acid drainage problem (Univ. of California, Berkley ). The issue of.  · Description: This manual was prepared to assist designers and operators of mine drainage treatment plants in the selection of processes, equipment, and procedures. Included is a review of the most popular neutralizing agents and the methods used to handle, prepare, and feed these alkalies. Also, a detailed engineering explanation of the various .
