Abstract
Metal mine wastes are among the most hostile environments for biota (high metal/metalloid levels, extreme pH, high salinity, low organic matter and nutrients). These wastes are often stored in open-air piles (mine tailings) that are classically restored with techniques of topsoil capping and then afforestation. An alternative is to promote the growth of native plant species directly in mine wastes, which help to create functional soil-plant systems, as previous studies showed. This work aimed to evaluate how technically reclaimed and abandoned spontaneously colonized metal(loid) mine tailings’ soils differ in their ability to mineralize carbon and nitrogen. The results show that the soils of both mine tailings are functional and have a similar potential to mineralize nitrogen. However, the soils of the restored reservoir showed a greater capacity to mineralize carbon.
