Physical properties used for identifying a mineral This site has a separate page for each of the most useful physical properties for identifying a mineral. Although some of these properties can be measured precisely (e.g. specific gravity), they are more commonly used qualitatively to identify minerals in the field, where no sophisticated equipment is available.

The chemical formula of the mineral Hematite is Fe 2 O 3. The letters describe the element type (Fe = iron, O = oxygen), and the subscripted numbers describe the amount of those atoms in each molecule. A Hematite molecule has 2 iron (Fe) atoms and 3 oxygen (O) atoms.
Higher concentrations in pyrope garnet cause a deeper red colour. Fe 3+ in octahedral sites. When the Fe 3+ ions are isolated by intervening ions it leads to a pale colour, such as the pale purple colour in strengite and coquimbite. Also the yellow-green colour in ferric silicates such as andradite.

Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel. Raw iron is alloyed with a variety of elements (such as tungsten, manganese, nickel, vanadium, chromium) to strengthen and harden it, making useful …
· Luster is also related to atomic structure and bonding within the mineral itself: metallic lusters tend to correspond with ionic bonds and nonmetallic lusters with covalent bonds. This makes it a fairly reliable way to identify minerals as it shows some of the chemical characteristics of the mineral.

Iron (/ ˈ aɪ ər n /) is a chemical element with symbol Fe (from Latin: ferrum) and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table is, by mass, the most common element on Earth, right in front of oxygen (32.1% and 30.1%, respectively), forming much of Earth''s outer and inner core.
Physical Properties of Iron Element Pure iron is known to be a soft metal, with a silver white or grayish color. Some of its most important properties are ductility, malleability and thermal conductivity. Malleability lets Iron be beaten into sheets, without cleavage and ductility makes it possible for thin wires to …
Galena is a lead sulfide mineral with a chemical composition of PbS. It is the world''s primary ore of lead and is mined from a large number of deposits in many countries. It is found in igneous and metamorphic rocks in medium- to low-temperature hydrothermal veins. In sedimentary rocks it occurs as veins, breccia cements, isolated grains, and ...
