Описание (английский):

ISO 2599:2003 specifies a titrimetric method for the determination of the phosphorus content of iron ores, using hexaammonium heptamolybdate (ammonium molybdate). This method is applicable to a concentration range of 0,10 % (m/m) to 5,0 % (m/m) of phosphorus in natural iron ores, and iron ore concentrates and agglomerates including sinter products. This International Standard provides a quality control method for the determination of phosphorus by titration, however, the method cannot be used for referee purposes.

Overview

ISO 2599:2003 - Iron ores: Determination of phosphorus content - Titrimetric method specifies a laboratory titration procedure for measuring phosphorus in iron ores, iron-ore concentrates and agglomerates (including sinter). The method uses hexaammonium heptamolybdate (ammonium molybdate) to precipitate phosphorus as ammonium molybdophosphate and covers the concentration range 0.10 % (m/m) to 5.0 % (m/m) phosphorus. ISO 2599:2003 is intended as a quality-control titrimetric method, not as a referee (dispute-resolution) method.

Key topics and technical requirements

Principle: acid decomposition of a test portion, separation of insoluble residue, removal of silica (HF/sulfate fusion), collection of phosphorus by precipitation with ammonium molybdate, dissolution of precipitate and back-titration of excess base.

Applicable range: 0.10–5.0 % P (method tested internationally on samples down to 0.03 % P).

Reagents: hydrochloric, nitric, perchloric, hydrofluoric and hydrobromic acids; ammonium molybdate solution; iron(III) reagents; standardized NaOH and HNO3 titrant solutions; CO2‑free water per ISO 3696.

Apparatus & sampling: routine laboratory glassware (ISO 648, ISO 1042); laboratory sample preparation and predried test samples per ISO 3082 and ISO 7764. Particle-size guidance: −100 µm (or −160 µm for ores with combined water/oxidisable phases).

Procedure controls:

Analysis at least in duplicate (independent repeats).
Include a blank and an analysis of a certified reference material (or suitable reference).
Specific test‑portion masses depend on expected P content (e.g., 1.0 g for low-P samples; 0.5 g for higher-P).
Modified procedure for samples with >18 mg titanium.

Quality and precision: Annexes provide flowsheet, repeatability/perm. tolerance derivation, and interlaboratory precision data.

Safety: uses hazardous acids (HF, HClO4) and oxidizers; follow appropriate lab safety and regulatory limits.

Applications and users

Practical for mineral laboratory quality control, metallurgical laboratories, ore producers, sinter and pellet plants, and secondary laboratories monitoring phosphorus in feed materials to steelmaking.

Useful where routine, cost-effective phosphorus determination in iron ore is required for process control, product specification, or incoming material inspection.

Not suitable as a referee method in legal disputes - use for routine QC, not arbitration.
