The siderite area to the right side is related to hard-ore category. The ore/waste identification at intervals of 6 m length is represented for blastholes 6–9 (from left to right); this makes five sections for holes 6 and 9 and four for holes 7 and 8 (right graph). These intervals are plotted in Fig. 12b with dark red markers.

Iron ore is a mineral substance from which the which metallic iron (atomic symbol, Fe) can be extracted. It is the most-used metal by both tonnage and purpose. Iron is usually found in the form of siderite (FeCO 3), goethite (FeO(OH), hematite (Fe 2 O 3 ), limonite (FeO(OH)·n(H 2 O), or magnetite (Fe 3 O 4 ).

Siderite decomposition experiments have been carried out for a wide range of metamorphic conditions (see van Zuilen et al., 2003 for an overview), and it is known that many factors will influence the breakdown of siderite, such as cation composition (Mn replacement for Fe), pressure, and redox state of the system.

Ankerite is named after Professor M. J. Anker, an Austrian mineralogist. Ankerite's formula is often written as CaFe(CO 3) 2; but there is actually a significant amount of magnesium amd manganese substitution for the iron and so the formula should be written as it is above.Ankerite forms in iron rich hydrothermal veins and metamorphic rocks with sulfides and other iron …
Siderite has Mohs hardness of 3.75-4.25, a specific gravity of 3.96, a white streak and a vitreous lustre or pearly luster. Siderite is antiferromagnetic below its Néel temperature of 37 K which can assist in its identification. It crystallizes in the trigonal crystal system, and are rhombohedral in shape, typically with curved and striated faces.
