| Popis: | Acid Mine Drainage (AMD) is an important source of pollution to the environment, characterized by a very low pH and high metal(loid)s concentration. The objective of this research was to evaluate the effect of three alkaline materials: marl, sandstone and calcareous crust on AMD neutralization and metal precipitation. To achieve this objective, a batch test was design, where a 5/10 alkaline material(g)/AMD(mL) ratio was used. In order to optimize the process, three particle sizes (2–10, 10–20 and 20−30 mm) of each material were used, and water samples were collected during the neutralization time. Due to the extreme pH of AMD used (pH |
