Where, Why, How ? 1- Life cycle of Ni Understanding the process and related chemical elements (Co, Sc, Mn) of natural enrichment In laterites (Fe-oxides and Case of laterites on ultrabasites silicates) (New Caledonia, Philippines) Ore processing of Ni-ores: the fine grained ore problem Extraction from soils and plants: Phytomining and agromining of Ni Impact of Ni on New Caledonia : biosphere • the only French production (except Au in French Guiana) • 10% of the world production of Ni • French mining operators : ERAMET (SLN) and small producers 8
A compilation of scientific papers on the genesis of Ni ore deposits in New Caledonia A compilation of scientific papers on phytomine will be produced shortly OTELo - LaBex RESSOURCES 21 9
International workshop announcement Ni geochemical cycle : from mining exploration to ecotoxicity October 17-19 – 2017 Nancy, FRANCE analytical advances in all topics related to low-temperature geochemistry of nickel and allied elements. understanding of key questions in the domain of Ni laterites from exploration to mining: • Ni mineralogy, including the behaviour of Ni during the serpentinisation and formation of Ni silicate ores (garnierite, talc-like, sepiolite) • The geochemical cycle of elements allied to Ni : Sc, Mn, and Co • Geometallurgy of Ni ores, including flottation and hydrometallurgy • Ni in soils and plants : phytomining, agromining, including advances in Ni isotope geochemistry, Ni hyperaccumulators, remediation of soils on ultrabasic rocks • Ni ecotoxicity and the hydrosphere
