Abstract
One of the most severe damages associated with mining is caused by the acid mine drainage (AMD) resulting from the oxidation of metal sulphides. In this study, the rehabilitation of AMD ponds was considered. Firstly, a remediation action was simulated in mesocosms, by replacing the water‐column by high quality water. This replacement is inefficient for toxicity removal. Secondly, six chemical treatments were simulated in laboratory microcosms using lime, limestone, kaolin, coal, cellulose and cement. The four least toxic treatments for Ceriodaphnia dubia were repeated in mesocosm containers deployed in the field. Physical and chemical parameters were measured and toxicity tests were conducted with Microtox®, C. dubia, Daphnia magna and locally collected Zooplankton. Both lime + limestone and lime + limestone + kaolin treatments removed similar quantities of metals from solution, being the two least toxic simulations.
