NewOreS is a project devoted to the: i) development of new models of ore deposition relevant for the W-Sn (Nb-Ta-Li) mineralisations, and intend to propose of new exploration guides for this type of mineralization, by building a fully comprehensive model for the behaviour of metals during crustal magmatic events, and ii) by understanding the behaviour of these metals at the hydrothermal stage, thanks in particular to by refinement of the in-situ analysis of trace elements especially Nb and Ta in oxides (SnO2, FeWO4) and in fluid trapped as fluid inclusions, and by building a new thermodynamic database for Nb and Ta species. iii) Finally, a major goal is the development of new flow sheets for the processing of low grade and fine-grained ores and tailings, in particular from a major W mine (Panasqueira) from already mined deposits thanks to new intensive flotation devices, the combination with centrifugal gravity separation, and search to develop a new energy saving mineral processing.
