Abstract
Natural materials or waste products with a high capacity for heavy metals can be obtained and employed of with little cost. The adsorption of Fe and Mn by the samples was influenced by compositions of adsorbing agents. The experimental results of desorption revealed that when the adsorption or precipitation occurs, there was no significant releasing from all adsorbing agents. In this study, the results suggest that recycled-concrete aggregate can be used successfully in the treatment of acid mine drainages with mixed metal-contaminated wastes.
