Full title and description

ISO 10204:2017 — Iron ores — Determination of magnesium — Flame atomic absorption spectrometric method. This International Standard specifies a flame atomic absorption spectrometric procedure for the determination of the mass fraction of magnesium in natural iron ores, iron ore concentrates and agglomerates (including sinter products).

Primary application: routine chemical analysis for magnesium in iron ore materials at mass fractions from about 0.010 % to 2.00 % (mass fraction basis).

Prepared by: ISO/TC 102/SC 2 (Iron ores).

Abstract

ISO 10204:2017 defines sample preparation and a flame atomic absorption spectrometric (FAAS) analytical procedure to determine magnesium content in iron ore materials. The standard covers scope, principle, reagents, apparatus, sample preparation and dissolution, calibration, measurement procedure, expression of results, precision and test report requirements. It is intended to provide a reproducible method suitable for quality control and laboratory reporting of Mg mass fraction in ores and concentrates.

Scope

This standard specifies a flame atomic absorption spectrometric method for the determination of the mass fraction of magnesium in natural iron ores, iron ore concentrates and agglomerates (including sinter products). It is applicable to magnesium mass fractions from approximately 0,010 % to 2,00 % and covers the steps from sample preparation and dissolution through calibration, measurement and reporting of results. The method is intended for routine laboratory use and for cases where comparability and traceability of Mg determinations in iron-ore-related materials are required.

Key topics and requirements

• Principle: flame atomic absorption spectrometry (FAAS) measurement after appropriate sample dissolution and matrix treatment.
• Scope limits: applicable mass fraction range ~0.010 % to 2.00 % Mg in iron ores and concentrates.
• Sample preparation and digestion procedures to ensure complete extraction of Mg from ore matrices.
• Calibration and standards: recommendations for calibration solutions, blanks and checks to ensure linearity and accuracy.
• Interference control and correction: procedures to identify and mitigate spectral and chemical interferences typical for iron-rich matrices.
• Performance characteristics: precision/reproducibility statements and criteria for result acceptance and reporting.
• Reporting: required information to appear in test reports (sample identification, preparation, result, uncertainty where applicable, method reference).

Typical use and users

Typical users are analytical laboratories, quality-control departments in mining and beneficiation operations, producers and traders of iron ore and ore concentrates, and standards bodies referencing a harmonized procedure for magnesium determination. The standard is used for routine compositional checks, acceptance testing, contractual verification and laboratory method harmonization.

Related standards

Standards and documents commonly referenced alongside ISO 10204:2017 include other ISO methods and sector documents for iron ores and mineral analysis (methods for other elements), laboratory quality management standards (for example ISO/IEC 17025 for testing laboratory competence), and regional/adopted versions published by national bodies and distributors. Users should consult product-specific specifications and related ISO/TC 102 publications for complementary test methods.

Q: What is this standard?

A: ISO 10204:2017 is an International Standard that specifies a flame atomic absorption spectrometric method for determining the mass fraction of magnesium in iron ores, concentrates and agglomerates.

Q: What does it cover?

A: It covers the analytical principle (FAAS), required reagents and apparatus, sample preparation and dissolution, calibration, interference control, performance characteristics (precision/reproducibility) and reporting requirements for Mg determinations in the stated materials and concentration range (about 0.010 % to 2.00 %).

Q: Who typically uses it?

A: Analytical and testing laboratories, mining and processing operations, ore producers, commodity traders, and parties needing a standardized method for contractual testing or quality control of magnesium in iron-ore products.

Q: Is it current or superseded?

A: ISO 10204:2017 is the 2017 edition (Edition 4) and, per ISO administrative review, this publication was reviewed and confirmed (remains current) in 2025. Users should check national adoption/confirmation notices for any regional variations.

Q: Is it part of a series?

A: ISO 10204 (base number) has earlier editions addressing related or prior techniques; however, the 2017 document (ISO 10204:2017) specifically addresses magnesium determination in iron ores. Other related ISO and CEN standards cover elemental analysis methods and documentation for iron ore testing.
