Mining companies that sell their products by the millions of tons could incur millions of dollars in revenue losses, if a slight bias related to the total iron analysis process were to be found. The profitability of any mining company depends on the assays that are run on exploration samples, concentrates, internal standards and/or reference materials.
The current International Standard Method, which remains widely accepted among peers, is the one entitled Iron ores -- Determination of Various Elements by X-ray Fluorescence Spectrometry -- Part 1: Comprehensive Procedure (ISO 9516-1:2003). However, there are a number of unveiled and corroborated limitations to the predominant version of this standard; it lacks adaptability when coping with recent advances in the fields of sample preparation by fusion and Wavelength Dispersive X-ray Fluorescence (WDXRF) spectrometry. Moreover, the preparation of standards made of pure oxides is a complex and time consuming task and the calibration ranges do not cover for the exploration samples.
