The method is applicable to phosphorus contents between 0,003 % (m/m) and 2 % (m/m) in natural iron ores, iron ore concentrates and agglomerates, including sinter products. The presence of arsenic, barium or titanium does not affect the result.
Abstract
Overview
specifies the molybdenum blue spectrophotometric method for determining the phosphorus content in iron ores. This International Standard is applicable to a range of materials including natural iron ores, iron ore concentrates, and agglomerates such as sinter products. The specified method quantifies phosphorus contents between 0.003% (m/m) and 2% (m/m). Importantly, the presence of elements like arsenic, barium, or titanium does not interfere with the results, ensuring reliable chemical analysis across diverse iron ore matrices.
