“…In metal isotope systems such as Si, Fe, Mo and Ge (Bergquist and Boyle, 2006;Opfergelt and Delmelle, 2012;Pokrovsky et al, 2014;Voegelin et al, 2012), weathering of continental bedrocks and soils is the main geochemical process responsible for driving heavy isotopes into the dissolved phase. Evidence for Ni isotopes has been found during the weathering of serpentinized peridotite in a tropical climate, leading to the incorporation of light Ni isotopes in lateritic regolith (Gall et al, 2013;Ratié et al, 2015). However, the influence of weathering conditions on the extent of fractionation still requires testing in order to better constrain the signatures of dissolved and particulate Ni exported to rivers.…”

“…Soil Ni availability is mainly controlled by the mineralogy and Nibearing mineral phases Chardot et al 2007;Quantin et al 2001). In strongly leached ultramafic soils, such as in Ferralsols, generally the Ni phytoavailability is low (Bani et al 2014;Cheng et al 2011;Das et al 1999;Echevarria et al 2006;Massoura et al 2006;Raous et al 2010;Raous et al 2013). However, in clay-mineral rich young soils (Cambisols) and saprolite materials, the Ni phytoavailable fraction is generally high (Raous et al 2010).…”

However, in clay-mineral rich young soils (Cambisols) and saprolite materials, the Ni phytoavailable fraction is generally high (Raous et al 2010). The main factors that influence Ni phytoavailability include: (i) the original parent material characteristics and its weathering history; (ii) soil composition, such as organic matter and clay content, thermodynamic conditions including pH and redox potential, and (iii) rhizosphere effects including root exudates (Antić-Mladenović et al 2011;Baker and Walker 1989;Chardot et al 2007;Echevarria et al 1998;Echevarria et al 2006;Ernst 1996;Massoura et al 2006;Massoura et al 2004).…”

Background Nickel (Ni) phytomining operations cultivate hyperaccumulator plants ('metal crops') on Ni-rich (ultramafic) soils, followed by harvesting and incineration of the biomass to produce a high-grade 'bio-ore' from which Ni metal or pure Ni salts are recovered. Scope This review examines the current status, progress and challenges in the development of Ni phytomining agronomy since the first field trial over two decades ago. To date, the agronomy of less than 10 species has been tested, while most research focussed on Alyssum murale and A. corsicum. Nickel phytomining trials have so far been undertaken in Albania, Canada, France, Italy, New Zealand, Spain and USA using ultramafic or Ni-contaminated soils with 0.05-1 % total Ni. Conclusions N, P and K fertilisation significantly increases the biomass of Ni hyperaccumulator plants, and causes negligible dilution in shoot Ni concentration. Organic matter additions have pronounced positive effects on the biomass of Ni hyperaccumulator plants, but may reduce shoot Ni concentration. Soil pH adjustments, S additions, N fertilisation, and bacterial inoculation generally increase Ni phytoavailability, and consequently, Ni yield in 'metal crops'. Calcium soil amendments are necessary because substantial amounts of Ca are removed through the harvesting of 'bio-ore'. Organic amendments generally improve the physical properties of ultramafic soil, and soil moisture has a pronounced positive effect on Ni yield. Repeated 'metal crop' harvesting depletes soil phytoavailable Ni, but also promotes transfer of non-labile soil Ni to phytoavailable forms. Traditional chemical soil extractants used to estimate phytoavailability of trace e l em en ts a re of limi t ed us e t o p re dic t Ni phytoavailability to 'metal crop' species and hence Ni uptake.

“…Moreover, Raous et al [45] identified willemseite, a Ni-rich form of talc, in their garnieritic sample from Barro Alto. Interestingly, smectite was not detected in our samples, whereas it has been found in "garnieritic" and soil samples coming from Niquelândia massif [31,42,45,46]. readily be transported and suspended in water, while the biggest and heaviest ones settle in the basin.…”

“…It is noticeable that all the identified clay minerals, as well as olivine, are potentially Ni bearing silicates commonly encountered in ultramafic soils [41][42][43][44][45][46][47], and goethite is known to be a great Ni scavenger in UM contexts [31,[48][49][50][51][52][53].

International audienceThe overall objective of this work was to assess the modification of Ni availability and lability consequently to anthropic activity. Surface waters were collected in two ultramafic complexes (Barro Alto and Niquelandia) from Goias State (Brazil) impacted by mining and metallurgical activities. For the nearly first time, Isotopic Exchange Kinetic technique (IEK) was performed on these natural water samples to quantify the pool of isotopically exchangeable Ni from the suspended particulate matter (SPM) in water, defined here as E-Ni(W). The SPM mineralogy was investigated by X-Ray Diffraction (XRD), Scanning and Transmission Electron Microscopy (SEM and TEM). This allowed to establish the link between Ni availability and its solid speciation. Goethite, chlorite, talc and serpentine were identified as the main Ni bearing phases in SPM far from metallurgy (Barro Alto site) while in samples located in the area influenced by metallurgy (Niquelandia) Ni was mainly associated to spherical micrometric particles, related to fly ash produced by the ore combustion. In Niquelandia samples 4,1, value was found ranging between 2.4 and 565 mu g L-1, while in Barro Alto E-Ni(W) was 62 mu g L-1, which corresponds to E-Ni values of 49,000 and 2350 mg kg(-1), in SPM from Niquelandia and Barro Alto, respectively. Moreover, IEK experiments highlighted differences in kinetic of Ni exchanges: the maximum E-Ni(W) value was reached after only 19 hours of interaction in Barro Alto sample, while in Niquelandia ones E-Ni(W) hardly reached 70 to 95% of the maximum after the same period of time. On the one hand, both the low proportion and high velocity of Ni exchanges observed in Barro Alto sample may be attributed to surface complexation on talc, serpentine, chlorite and goethite. On the other hand, both the higher proportion of exchangeable stock and slower isotopic exchanges should be mostly attributed in Niquelandia samples to Ni interaction with the anthropogenic spherical and porous particles of Fe-Mg-Si-Al composition, related to FBA released by metallurgic activity
