Abstract |
The research investigated treatment methods for ferric iron acid mine drainage. One of the most promising techniques studied was combination limestone-lime neutralization. To date, neutralization has been shown to be the most economical treatment method to remove iron, aluminum, and acidity. Lime treatment has received the majority of research attention. However, limestone treatment offers several distinct advantages over lime; namely higher density, lower volume sludges, cheaper raw material costs, easier handling. Conversely, the biggest disadvantages to limestone are its relatively inefficient reaction rate. In an effort to cover a broader spectrum of application, the report discusses the combination of the two processes. |
