Abstract: Acid mine drainage (AMD), has long been a significant environmental problem resulting from the microbial oxidation of iron pyrite in presence of water and air, affording an acidic solution that contains toxic metal ions. The main objective of this study was to remove and recover metal ions from acid mine drainage (AMD) by using lignite, a low cost sorbent. Lignite has been characterized and used for the AMD treatment. Sorption of ferrous, ferric, manganese, zinc and calcium in multi-component aqueous systems was investigated. Studies were performed at different pH to find optimum pH. To simulate industrial conditions for acid mine wastewater treatment, all the studies were performed using single and multi-columns setup in down flow mode. The empty bed contact time (EBCT) model was used for minimizing the sorbent usage. Recovery of the metal ions as well as regeneration of sorbent was achieved successfully using 0.1 M nitric acid without dismantling the columns. < copyright > 2006 Elsevier B.V. All rights reserved.

Abstract: This paper describes the genesis, structure and classification of natural zeolites, including their most relevant properties such as porosity, adsorption and ionic exchange. The use of natural zeolites in the treatment of effluents containing heavy metals is reviewed based on current literature. These uses are focused on mineral-metallurgical effluents and mercury pollution related to artisan mining activities. The study shows that natural zeolites are efficient in removal of heavy metals in metal mining effluents, can be produced and improved at a low cost, and can also be used to adsorb mercury vapors from ovens used to fire amalgams.
