| Abstract |
The nation-wide problems related to acidic discharges from coal mining operations are well documented in both popular and technical literature. Neutralization is and will continue to be a necessary short-term measure in numerous instances, while long-range programs are being developed to prevent and/or arrest acid production at the source. Considerable effort has been expended in investigating the neutralization of acid mine drainage with limestone, lime, and soda ash. A combination limestone-lime process has been shown to have cost advantages with improved effluent quality and sludge settling characteristics. This document is the final and summary report on the neutralization studies. Utilizing a full scale neutralization plant, the effect of detention time, sludge recirculation, flow pattern, and treatment pH have been observed using limestone and lime separately and in combination. Data have been accumulated on highly acidic ferric iron acid mine drainage to determine the most economical method of treatment. Plant operation indicates that combination limestone-lime treatment with sludge recirculation on both treatment lines is the most economical scheme of treatment. |
