“…Ore is processed in the Malmberget concentrator in two lines: one for magnetite dominated ore (FAR) and another for hematite dominated ore (HAR). Lund (2013) developed a preliminary geometallurgical classification of the ore body based on modal mineralogy and mineral textures (see also Lamberg and Lund, 2012;Lamberg et al, 2013;Lund et al, 2013). This model, however, did not take into account comminution properties.…”

“…Alternative methods such as quantitative XRD by Rietveld analysis (Mandile and Johnson, 1998) and the element-to-mineral conversion method (Lamberg et al, 1997;Lund et al, 2013;Paktunc, 1998;Whiten, 2007) require simpler and faster sample preparation and can be non-destructive. Additionally, if the aim is the estimation of mineral grade, they may offer better value than automated mineralogical analysis system only if they can fulfill the requirements on trueness and precision.…”

“…Lund et al . () described an analytical protocol that can be applied to iron ores for producing a modal mineralogy from XRF results. They based the element to mineral conversion on a set of linear expressions and least‐square equations using EPMA mineral determinations, going on to validate the modal results against QEMSCAN ® analyses.…”

Advances in the chemical, crystallographic and isotopic characterisation of geological and environmental materials can often be ascribed to technological improvements in analytical hardware or to innovative approaches to data acquisition and/or its interpretation. This biennial review addresses key laboratory methods that form much of the foundation for analytical geochemistry; again, this contribution is presented as a compendium of laboratory techniques. We highlight advances that have appeared since January 2012 and that are of particular significance for the chemical and isotopic characterisation of geomaterials. Prominent scientists from the selected analytical fields present publications they judge to be particular noteworthy, providing background information about the method and assessing where further opportunities might be anticipated. In addition to the well-established technologies such as thermal ionisation mass spectrometry and plasma emission spectroscopy, this publication also presents new or rapidly growing methods such as electron backscattered diffraction analysis and atom probe tomographya very sensitive method providing atomic scale information.
