Deposits: Characteristics of Ni-Co Mineralizations in Lateritic Profiles
Currently Ni-Co laterites account for the 60 to 70 % of the world’s terrestrial Ni-Co resources. Nickel and cobalt are strategic metals of vital importance in many modern industrial applications. My project will deal with mineralogical and chemical features of the Ni-Co laterite deposit of Wingellina (Western Australia), because its complex mineralogy could be a challenging issue during the metallurgical treatment of the ore. I intend also to: 1) study Ni and Co deportment in lateritic environments, 2) try the bio-leaching process on Wingellina ore, 3) reconstruct the climatic conditionsduring the lateritization process in Western Australia.
