Limonite: an iron oxide used as pignment and iron ore. Commercial mining of limonite as a source of iron is no longer done in areas where reasonable deposits of hematite and magnetite are present or …
The best known are hematite and pyrite, two iron-based minerals that are often used for ornamental purposes. Hematite is iron oxide that gets its name from the Greek word for blood, since it is red when sliced thinly or powdered. Hematite forms in the rhombohedral crystal system, which is the same crystal structure as sapphire and ruby.
Iron pyrite is a naturally pure and hugely useful ore of iron, finding applications in areas as diverse as photovoltaic cells, brake pads and as a glass colourant. African Pegmatite is a leading supplier of iron pyrite, with the ability to provide the material in a range of grind sizes suited to any operational need.
generally: Most common iron ore mineral, usually as soft blue hematite but locally schistose and specular (Bayley et al., 1966). The Vulcan Iron Formation in this range carries earthy red hematite, specularite, martite, and magnetite (Carr and Dutton, 1959; James et al., 1961). Martite is common in the Brier Slate member of this

Magnetite and hematite are common iron-oxides, being found in sedimentary, metamorphic and igneous environments and being associated with a wide variety of deposits styles, including orogenic gold, iron-oxide copper-gold and iron-ore deposits. While the magnetic and mass properties of magnetite and hematite have been
mined ore is mainly magnetite, which is 86.82% of total iron in the ore. The ore contains 1.62% sulfur impurity; thus, the ore is considered as magnetite ore with high sulfur hard-to-upgrade. 3.2. The Type and Structures of Ore 3.2.1. The Type of Ore The iron ore can be divided into two main types according to their mineral con-

Magnetite is an important iron-ore mineral in Ontario, Quebec and Labrador. Elsewhere, grains of magnetite are concentrated in black sand beaches that make up some shoreline deposits; In some parts of the world, large black sand deposits have been worked as iron-ore, as the magnetite can easily be extracted by electro-magnets.

Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3). Iron ore is the source of primary iron for the world's iron and steel industries.
