The Ni-hyperaccumulating species <em>Odontarrhena muralis</em> is widely distributed on ultramafic soils in Serbia, and could be a promising candidate for Ni agromining. In the present study, efficiency of a hydrometallurgical process for Ni recovery using biomass of <em>O. muralis</em> wild population through the synthesis of Ni salts from plant ash in the form of ammonium nickel sulfate hexahydrate, Ni(NH<sub>4</sub>)<sub>2</sub>(SO<sub>4</sub>)<sub>2</sub> 6H<sub>2</sub>O – (ANSH) was assessed. The average Ni content in the plant from ultramafic sites in West Serbia was up to 3.300 g kg<sup>-1</sup>. The mass yield of ANSH crystals from the crude ash was ~12 % with the average purity of 73 % were obtained. By optimizing the purification process before precipitation of ANSH crystals, it is possible to obtain salt crystals of higher purity, which increases the economic profitability of this process. The results of this preliminary study on wild population of <em>O. muralis</em> show the increased potential for implementation of phytomining practices as an alternative way of Ni extraction on ultramafic sites in Serbia.</p>}, number={5}, journal={HEMIJSKA INDUSTRIJA (Chemical Industry)}, author={Marković, Branislav and Ranđelović, Dragana and Jovanović, Gvozden and Tomović, Gordana and Jakovljević, Ksenija and Mišljenović, Tomica and Sokić, Miroslav}, year={2021}, month={Nov.}, pages={285–296} }
