Ans. Hematite and Siderite are the ores that come from Iron. Hematite contributes 37% of ore and siderite contributes very less as it is low-grade iron ore. Hematite ore consists of 60 to 70% of iron ore which has a red & brown colour. It is known for its finest quality. The Siderite is a brown colour that has 48% iron with impurities.
Uses of Ankerite. Ankerite has only limited industrial use, mostly in special construction or refractory materials. It might be used as very poor iron ore in the past, together with siderite. Occurrence of Ankerite. Ankerite is known from many localities, but only some have yielded fine crystals:
Vein deposits of dolomite occur with quartz and other common vein minerals, such as calcite, magnesite, fluorite, siderite, and sphalerite, or with metallic ore minerals such as galena, pyrite and chalcopyrite. Although uncommon, when dolomite occurs in altered ultramafic igneous rocks, it may be associated with magnesite, serpentine, and talc.
Siderite belongs to the calcite group and forms series with rhodochrosite and magnesite. Diagnostics This stone is too soft to be cut and is hence rarely faceted as a gemstone.

Concretionary siderite in a clay-ironstone from Farmsen, Germany. Width of sample 9 cm. TUG 1608-1779. Siderite is some shade of brown or brownish yellow. It is more dense (3.96) than other common carbonates because of iron content. It occurs as an earthy mass or as concretionary nodules (clay ironstone) in iron-rich sedimentary rocks.
Calcite is almost as common in our society as it is in nature, its uses ranging from medicine and animal feed, to Michelangelo's 'Pieta,' and highway overpasses. To a remarkable degree, human society mimics marine organisms in the sense that we rely on calcite to construct many of the 'hard' parts of our society, in the form of marble ...
