“…Due to the insatiable demands for commodity metals, from 5×10 9 to 14×10 9 tons of tailings are accumulated annually worldwide, which resulting significant damage to the environment around the tailings storage area once the mine was closed [1,2]. Covering these tailings landscapes with stable and functional ecosystems seemly a suitable strategy to decrease the environmental risks of mine tailings [3]. However, direct reclaiming of the abandoned tailings area is unsustainable and infeasible due to the high toxicity content of metals, harsh pH conditions, deficiency of nutrient contents and poor physical structure, which hindering the colonization of microbial and plant [3].…”

The worsening global climate change appeal of a low-carbon technology in tailing landscapes rehabilitation for the sustainable goal. This study explores smoldering to construct soil-like substrate in an eco-engineering tailings manner. The obtained tecnhsoil exhibit low metals bio-toxicity, elevated physiochemical properties and improved nutrients statue, which is significant for the subsequent revegetation of the mine tailings landscapes. Due to the self-sustaining characteristic of smoldering and the carbon-neutral nature of biomass energy, the article presents here are exactly a contribution to achieve carbon neutrality.

“…The development of Technosols using these amendments may reduce the metal(oid) bioavailability and acid mine drainage (AMD). Moreover, these Technosols allow the establishment of new vegetation, improving the soil fertility and increasing the diversity of microbial communities as well as reducing wind and water erosion [9,10].…”

Nitrogen Assessment in Amended Mining Soils Sown with Coronilla juncea and Piptatherum miliaceum

et al. 2022

Metalliferous mining activities generate a large amount of waste. This waste usually has high concentrations of pollutants such as metal(oid)s associated with the extractive processes, which, if not properly treated and reclaimed, put the ecosystem and the population at risk. One of the most used techniques for mine waste reclamation is aided phytostabilization, which is based on the use of plants that immobilize metals in the soil/roots aided by the use of amendments to improve the soil properties to favor plant growth. Although amendments increase nutrients and improve the soil properties, the concentration of these nutrients—especially N, the most limiting plant nutrient—decreases over time. Thus, this study focused on the evaluation of the relationship between different combinations of amendments (compost, biochar, zeolite and limestone) and plant growth (we introduced Coronilla juncea and Piptatherum miliaceum) on the evolution of soil N over time as well as the influence of C. juncea on soil N fixation. The results showed that the addition of amendments improved the soil characteristics in all plots favoring the growth of C. juncea and P. miliaceum. The compost provided higher concentrations of total N, nitrites, nitrates and ammonium due to the nature of this amendment and the biochar was less in measure. The limestone helped to elevate the pH and the zeolite controlled the exchangeable ions. Soils from C. juncea showed higher concentrations of N forms, suggesting that this legume contributes to the enrichment of soil N, likely due to biological fixation. Hence, the combinations limestone-zeolite-compost and limestone-zeolite-compost-biochar were the most suitable treatments for improving the soil fertility and favored plant growth. In addition, C. juncea seems to be a good candidate for reclaiming mining environments.

“…Línea de semillas P. miliaceum, es una especie comúnmente encontrado entre la vegetación pionera de los depósitos mineros en áreas semiáridas (Morugán-Coronado & Soriano-Disla, 2021;Parraga-Aguado & González-Alcaraz, 2015) y presenta un buen desarrollo vegetativo en estos emplazamientos. Además, P. miliaceum tiene una gran capacidad para inmovilizar metal/oides en la rizosfera, caracterizándose también por su baja translocación de estos elementos a la parte aérea de la planta (Shahrokh et al, 2023a).…”
