This paper reviews the occurrence of platinum-group elements nanoparticles (PGE-NPs) in mantle-hosted chromite deposits, showing that PGE-NPs are more frequently found in these deposits than previously thought. A comparison ...

Trace element distribution and Zr-in-rutile temperature have been investigated in accessory rutile from stratiform (UG2, Merensky Reef, Jacurici), podiform (Loma Peguera), and metamorphic chromitites in cratonic shields ...

The glycerol hydrogenolysis reaction was performed in a continuous flow trickle bed reactor using a water glycerol feed and both copper chromite and Cu/Al2O3 catalysts. The commercial copper chromite had a higher activity ...

Two districts of stratiform chromite deposits are situated near the northern margin of the São Francisco craton. The ultramafic host rocks are remnants of early Precambrian layered complexes that intruded Archean gneissic ...

We report new results of a combined focused ion beam and high-resolution transmission electron microscopy (FIB/HRTEM) investigation of platinum-group elements (PGE)-rich base-metal sulfides. The Ni-Fe-Cu base-metal sulfides ...
