ofph osphorusbearing minerals in iron ores that reduce ore qu ality below that required for steel making. Probl ems can also arise from the presence of finelayer silicates such as kaolin.talc.orsericite when flotationis used for ore concentration.Th ese minerals also tend to
Steel production is the driving force for almost all iron ore demand. However, technological changes in iron ore mining through to the production of ﬁ nished steel have been major contributors in determining the quantities and properties of the iron ore demanded. There are two technologies
ORE MATERIALS: PRIMARY AND SECONDARY MINERALOGY OF
The accompanying table from Fergusson (1985) shows the most important ore minerals, classified between the abundant metals (iron, aluminum, titanium, manganese, magnesium) and the scarce metals (subdivided between chalcophile, siderophile, and lithophile chemical elements). The abundant ore metals mainly occur as metal oxide minerals, except for
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 color from dark grey, bright yellow, deep purple, to rusty red. The iron itself is usually found i. Iron Ore Processing.
