New White Paper – Iron Oxide Speciation

Our second white paper is out looking at the difficult problem of iron-oxide speciation using automated mineralogy. The distinction between hematite and magnetite has long been a difficult task using SEM-based automated microscopy but the use of fully quantified EDS methodologies and finely tuned step sizes allows for the successful resolution of even finely intergrown complex iron-oxide textures. The abstract is below with a link to the full pdf here. This white paper is published in conjunction with Carl Zeiss Microscopy Ltd.

Abstract

Distinction between hematite and magnetite using automated mineralogy has long been a difficult task. However, the advent of Mineralogic using a fully quantitative EDS mineral classification methodology, and thus mineral classification by the minerals stoichiometry, has provided a more precise classification of the samples mineralogy. This paper outlines the advantages of using Mineralogic in characterisation of Iron ore samples and discusses the importance of the step sizes required to successfully characterise the fine inter growth textures associated with iron samples.
