ABSTRACT:
Methods are provided for inhibiting the production of acid in acid mine waters by controlling the growth of Thiobacillus ferrooxidans in the mine waters by adding an effective amount of acrolein. This will reduce acid mine drainage to other aqueous systems. The methods comprise adding from about 0.1 to about 10 parts acrolein per million parts of the mine water for which acid production inhibition is sought.
