Abstract

Metal mine wastes are among the most hostile environments for biota (highmetal/metalloid levels, extreme pH, high salinity, low organic matter and nutrients). Thesewastes are often stored in open-air piles (mine tailings) that are classically restored withtechniques of topsoil capping and then afforestation. An alternative is to promote thegrowth of native plant species directly in mine wastes, which help to create functional soilplant systems, as previous studies showed. This work aimed to evaluate how technicallyreclaimed and abandoned spontaneously colonized metal(loid) mine tailings’ soils differin their ability to mineralize carbon and nitrogen. The results show that the soils of bothmine 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
