How to minimize energy and mass fluxes Preserve the environment

Objectives : Insufficient recycling, increasing demand >>> New mines

Source rock Transport (fluid, magma) Concentration (ores) Exploitation (mine) Extraction (mill) Separation (plant) Concentrate Metal salt or alloy Dispersion transport (waters) Geo-availability Bio-concentration Bio-availability Eco-toxicity

x 102 to 105 Evaluate the environmental Impact and risks Remediate contaminated soils Improve clean and efficient extraction Understanding concentration processes Life cycle of strategic elements (REE, Ge, In, Nb, Ta, ….) Numerous knowledge gaps

Where, Why, How ? Understanding the process

• f natural enrichment

In laterites (Fe-oxides and silicates) 1- Life cycle of Ni and related chemical elements (Co, Sc, Mn) Case of laterites on ultrabasites (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 biosphere

New Caledonia :

• the only French production

(except Au in French Guiana)

• 10% of the world production of Ni
• French mining operators : ERAMET (SLN)

and small producers

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
