Abstract
Water soluble detergents such as sodium lauryl sulfate (sls), which can sorb to pyritic materials, have been successfully used by the mining industry for acid drainage prevention in coal refuse. Detergent control of acid drainage from refuse may be uneconomical, however, at sites where extensive rainfall or ground water movement results in rapid sls washout. In this study, the performance of two alternative acid control chemicals, sodium benzoate and potassium sorbate, was compared with the performance of sls in pilot-scale experiments with extensively leached, fresh coal refuse.
