ISO ISO 2599 2003 Iron ores — Determination of phosphorus content

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.

Selective Reduction of Iron and Phosphorus from Oolitic Ore

The phosphorus content is at in the metallic phase of ore specimen mixed with the graphite powder (Fig. 1a spectra 1 and 2) which is much higher than that upon reduction in a carbon monoxide atmosphere (Fig. 1b spectrum 2).However there is no full reduction under these conditions because iron and phosphorus are also present in the oxide phase.

Phosphorus in different types of ore sulfides in the iron deposits

The Leveniemi iron ore occurs mainly in sedimentary rocks. In the coexisting ironcopper ore deposits at Tjaarrojaakka high phosphorus contents are often northern Sweden there is also apatite enrichment in the ores and wall rocks which lie below the Kirunatype ores. These ores are regarded as sedimentary.
