Mandatory application of the iron ore fines schedule as per the IMSBC Code requirements: applies only to iron ore cargoes containing BOTH: (a) 10% or more of fine particles less than 1 mm (D 10 ≤ 1 mm) ; and (b) 50% or more of particles less than 10 mm ( D 50 ≤ 10 mm). However, if the total goethite content is 35% or more by mass, iron ore fines may be carried in accordance with the
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)

Nov 15, 2016 The recovery of fine iron ore by magnetic separation will decrease with decreasing particle size because the magnetic susceptibility of magnetic particles decreases with a decrease in particle mass. There is an example of an Australian iron-ore operation that introduced beneficiation of fine haematite, -100 m, by using WHIMS2
