Nanoscale partitioning of Ru, Ir, and Pt in base-metal sulfides from the Caridad chromite deposit, Cuba Abstract 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 (BMS) studied are millerite (NiS), pentlandite [(Ni,Fe)9S8], pyrite (FeS2), and chalcopyrite…

2019: Ni-bearing phyllosilicates (“garnierites”): New insights from thermal analysis, micro-Raman and IR spectroscopy
Ni-bearing phyllosilicates ("garnierites"): New insights from thermal analysis, micro-Raman and IR spectroscopy Abstract Ni-Mg-phyllosilicates, so-called “garnierites”, are significant Ni ores in Ni-laterite deposits worldwide. In addition, they are the natural analogues of synthetic catalysts involving Ni and phyllosilicate substrates used in reactions for the remediation of greenhouse gases. However, the nomenclature, classification and characterisation of…
