“…There is also growing interest and research on the rehabilitation, and long-term management/closure plans of the alkaline waste repositories, especially for red mud. [35][36][37][38][39][40][41] The spontaneous revegetation of alkaline residues often occurs with rare orchid-rich calcareous grassland, a habitat type which has declined dramatically in Europe in recent decades. [42][43][44][45] Calcium-rich, nutrient-poor substrates often have high floral diversity and, in many cases, alkaline residue disposal sites can obtain formal conservation designations.…”

With an estimated annual production of two billion tonnes globally, alkaline industrial wastes can be considered both major global waste streams, and materials that offer significant options for potential resource recovery. Alkaline wastes are usually derived from high temperature production (e.g. steel and alumina) or disposal (e.g. incineration) processes and are increasingly abundant given rising global demand for steel and alumina and the drive for waste incineration in some jurisdictions. Although relatively long-standing afteruses have been adopted for these materials (e.g. steel slag use as an aggregate) providing opportunities for value recovery, they are not sufficient to consume all residue arisings or limit potential environmental impacts.These impacts can include the generation of fugitive dusts, challenges associated with revegetation, and impacts on the water environment. These wastes can produce highly alkaline leachates that are enriched with trace metals (e.g. As, Cr, Mo, V) and persist over decades after site closure. Vanadium, one of the most severe ecotoxins in the leachate, is also a valuable commodity for renewable energy technologies, unifying the often divergent needs of resource recovery and remediation. Case studies are described illustrating routes to resource recovery from wastes from two major industrial sectors; steel production and alumina production.

“…It is known that the concentration of light REEs in the roots of vascular plants is usually higher than in other plant organs, including shoots (Carpenter et al 2015;Grosjean 2019;Mikołajczak et al 2017;Nazreen et al 2017;Thomas et al 2013). However, the accumulation of these in leaves and stems, being the main organs of photosynthesis, can have major consequences for plant growing (Thomas et al 2013).At the same time, effective REE transport from the root system to the leaves is one of the most important criteria in an effective phytoextraction strategy: with the active accumulation of REEs in the aboveground parts of plants, these are easily removed from the environment (Mikołajczak et al 2017).Research on abandoned wastelands has shown that Poaceae are the dominant plant family there (Mishra et al 2017;Singh 2011). These grasses have an extensive root system, which supports the rapid colonization of abandoned lands (Chauhan and Ganguly 2011;Mishra et al 2017;Singh et al 2013).…”

This paper presents the results of an assessment of the ground and plant chemistry in disturbed areas exposed to impacts from adjacent rare metal ore concentration waste storage facilities.The focus of research were areas with sparse vegetation cover near the site of the first tailing storage facility (TSF), which is not exploited from 1985. In the summer of 2019, on three key plots within the study area, plant samples were collected at a small distance from the TSF and operating process transport routes (<1 km). Based on a bulk chemistry analysis of the ground samples, concentration values were measured above the background values adopted for the region’s soil parent rock materials, and in the absence thereof, the clarkes of elements in acidic (SiO2 >60%) rocks found in the earth's crust. Grounds were found to be rich in Ta, Ce, La, Th, Zr, Nb, which are also present in the loparite ores of various origins mined by the operation.The chemistry was examined of Salix spp. commonly found both in the study area and in the region as a whole and of wavy hair grass Avenella flexuosa L. An abnormally high level of zinc accumulation was observed in Salix lapponum (>850 mg/kg, biological absorption coefficient (BAC) >4), and technological transport influence was proposed as a possible cause. High paired correlation coefficients of rare and trace elements with Al and with each other (>0.9) in the bulk chemistry analysis of Salix spp. indicate the likelihood of deposition of minerogenetic dust particles. Based on the observed values of the BAC, the plants were classified into biological accumulation (BAC >1) and biological uptake (BAC <1) classes and the latter was found to be dominant.

“…Trabalhos envolvendo seu uso como adsorvente contemplam avaliações realizadas na forma como foi descartada nas barragens de rejeitos, "in natura" (WANG, PAN, XU, 2020), e após receber pré-tratamentos para minimizar seus compostos indesejáveis (e.g., sódio), reduzir sua alcalinidade e aumentar seu potencial adsortivo (PICHINELLI et al, 2017;NARAYANAN, VENKATESAN, POTHEHER, 2018;YANG et al, 2020). Sua aplicação em 14 solos contaminados com elementos potencialmente tóxicos envolve avaliações para fins de uso na revegetação, remediação e redução do foco de poluição das áreas contaminadas (LOPES et al, 2016;GAUTAN, AGRAWAL, 2017;MISHRA et al, 2017;TANEEZ, HUREL, 2019).…”
