In fact, our results support the idea that S. minima might be considered a hyper-accumulator of nickel, as it is able to accumulate 16.3 mg g −1 (whole plant DW basis). Our results also showed a two-steps uptake pattern of nickel, with a fast uptake of nickel at the first 6 to 12 h of being expose to the metal, followed by a slow take up phase until the end of the experiment at 144 h.

Plant and Soil Prospecting for Nickel

The nickel in the Oregon deposit occurs in both the peridotite and the overlying soil. A deep lateritic-like soil is developed locally on the peridotite and serpentine and constitutes the ore. The average nickel content of the lateritie soil is less than one per cent, whereas the nickel content of the peridetite is about 1 to 1.5 per cent. The nickel occurs as garnierite (Mg, Fe, Ni, Mn)3(OH)4 Get price
