Oct 01, 2017· Sampling from stationary lots such as ships or stockpiles is not permitted by ISO 3082, as it is impossible to drive a sampling device through the lot depth and extract a full column of ore. ISO 3082 therefore recommends only to extract samples as the ore is being transported to or from a ship, stockpile, bunker or silo.

Sampling practice and theory

For the iron ore concentrate, the GBT-10322.1-2000 standard stipulates we can use the auger sampling system to sample unless the auger sampler can reach the bottom of the iron ore storage and the auger hopper which is filled with iron ore. TOP-SAMPLER promises that our all sampling systems can meet this requirement and the sampling procedure is random and effective.

Iron ores — Sampling and sample preparation procedures

Description. Iron Ore (fines) Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, deep purple, to rusty red. The iron itself is usually found in the form of magnetite (Fe 3 O 4), hematite (Fe 2 O 3), goethite (FeO(OH)), limonite (FeO(OH).n(H 2 O)) or siderite (FeCO 3).
