Comparison of bauxites from Jamaica, the Dominican Republic and Suriname

Determination of Trace Elements in Bauxite Using Laser Ablation‐Inductively Coupled Plasma‐Mass Spectrometry on Lithium Borate Glass Beads

“…17% lower, comparable to the average difference with the INAA data of Grant et al . (). We attribute the systematic offsets for this reference to its low Si content (0.68% m/m SiO 2 , Govindaraju ), which may have affected the use of this element as internal standard, either due to analytical uncertainty in the recommended value for this bauxite reference material, or to the low count‐rate ratio of 1.8 for the pre‐ablation blank and the analyte signal recorded in our measurement.…”

“…, Sampaio and Enzweiler ) and INAA data for BX‐N (Bédard and Barnes ), NIST SRM 69b (Korotev ), NIST SRM 696 and NIST SRM 698 (Grant et al . ). All reference data were extracted from the GeoReM database.…”

“…For FeR-2, we also used a set of compilation values that were certified or provisionally recommended by the Canadian Certified Reference Materials Project (CCRMP) under the auspices of Natural Resources Canada (NRCan). Additional literature data included for comparison are solution ICP-MS values reported for the three NIST RMs (Wang et al 2013) and FeR-2 (Yu et al 2003, Sampaio andEnzweiler 2015) and INAA data for BX-N (B edard and Barnes 2002), NIST SRM 69b (Korotev 1996), NIST SRM 696 and NIST SRM 698 (Grant et al 2005). All reference data were extracted from the GeoReM database.…”

“…Trace element contents in bauxites have been determined by a variety of methods including instrumental neutron activation analysis (INAA) (Vukotić , Korotev , Grant et al . ), X‐ray fluorescence spectrometry (XRF) (Mordberg et al . ) and inductively coupled plasma‐atomic emission spectrometry (ICP‐AES) (Boulangé and Colin , Ochsenkühn‐Petropoulou et al .…”

“…This can be used as a guide for exploration or processing strategies. Trace element contents in bauxites have been determined by a variety of methods including instrumental neutron activation analysis (INAA) (Vukoti c 1983, Korotev 1996, Grant et al 2005), X-ray fluorescence spectrometry (XRF) (Mordberg et al 2001) and inductively coupled plasma-atomic emission spectrometry (ICP-AES) (Boulang e andColin 1994, Ochsenk€ uhn-Petropoulou et al 1990). In recent years, inductively coupled plasma-mass spectrometry (ICP-MS) has become the technique of choice because it allows the determination of a comprehensive set of elements that includes transition metals, high field-strength elements (HFSE) and rare earth elements (REE) at low mass fractions (e.g., Horbe and Anand 2011, Gu et al 2013, Wang et al 2013, da Costa et al 2014, Mongelli et al 2014, Ahmadnejad et al 2017).…”
