A wide variety of plants are able to extract nickel (Ni) from soils and accumulate this metal in their aerial parts. Some plants, e.g. Alyssum murale, growing in the Balkans, contain 1% of Ni, while tropical trees, e.g. Rinorea bengalensis accumulate 3% Ni in their leaves. Hydrometallurgical processes have been developed to recover Ni in the form of metal or salts, starting from A. murale. They include 1) a combustion step, to obtain ashes, containing 15 to 20% Ni, 2) a leaching step and 3) purification. The whole chain has been thoroughly investigated, and the processes up-scaled to the pilot scale. This presentation shows how the process has been extended to tropical plants and gives highlights for the further development of agromining.
