Prediction of the relative rates of acid generation and neutralization is required to determine if and when acidic drainage will occur for mining waste. Results of laboratory kinetic tests are routinely used to predict the long-term weathering rates

The net result of acid-generating and-neutralizing reactions within mining wastes is termed acid rock drainage (ARD). The oxidation of sulfide minerals is the major contributor to acid generation. Dissolution and alteration of various minerals can co

Arsenic is often present in a variety of forms in sulfide mineral deposits and can become a soluble constituent of mine drainage due to oxidation reactions taking place in mine workings and waste deposits. Its removal from solution must be carried ou
