Iron Ore

Iron ore particle testing standards are published by ISO. They include sampling of slurries and vocabulary related to iron ore and direct reduced iron.

ISO 16742:2014

Iron ores - Sampling of slurries

ISO 16742:2014 sets out the basic methods for sampling fine iron ore of nominal top size 1 mm that is mixed with water to form a slurry. At very high ratios of fine solids to water when the material assumes a soft plastic form (about 80 % solids depending on the particle size distribution of the solids), the mixture is correctly termed a paste. The procedures described in ISO 16742:2014 apply to sampling of iron ore that is transported in moving streams as a slurry. These streams can fall freely or be confined in pipes, launders, chutes, spirals, or similar channels.
