Hematite (from Greek: αιμία, Haima, blood) is a mineral which is mainly composed of ferric oxide crystals (iron (III) oxide, Fe2O3), one of the iron oxides. It comes in addition to other varieties like the red blood stone and gray-black to black gloss iron and iron oxide. The mineral has a hardness between 5 and 6. The so-called stripe, stripe or color, the color issuing the mineral to rub on an unglazed porcelain dish, usually a characteristic blood-red - the mineral it takes its name. It may contain trace amounts of magnesium, manganese and titanium mineral. Hematite comes both before and going as mineral in sedimentary layers. It is often the cause of reddening of many rocks. Along with hematite often other iron ores such as magnetite, limonite and iron ore. If magnetite is converted to hematite is called martite. The mineral occurs worldwide, in Europe, in Germany, among others in the area of ​​the Lahn which is the world's largest concentration of iron ores in the Eifel Mountains, the Harz Mountains and the Thuringian Forest. Furthermore, in England in Cumberland and North Lancashire, in Belgium in Vezin and Namur, on the Italian island of Elba and in Spain. In Africa, Algeria is a significant producer and in the United States of America it is found at the Upper Lake and at the Missouri. More than half of world production now comes from China, Brazil and Australia. In addition, the mineral is also in high concentration on the surface of the planet Mars. This creates the typical orange-red color of the "Red Planet". The mining of hematite is one of the earliest mining of humanity: the powdered mineral was found in about 80,000 years old graves. Both on the Greek island of Thassos and in the places Rydno in Lovas in Poland and Hungary, have grooves known from the Palaeolithic. Also in Germany, traces of prehistoric mining of similar size found in Bad Sulzburg and in Münster from the time around 5000 BC that the Linear Pottery Culture at the Topline are due. The Etruscans had already abundant prevent iron shine known on the island of Elba.

Pyrite or iron pyrites is a mineral with the formula FeS2 (chemical name: iron disulfide). It is an important mineral iron ore and sulfur. It is often well-formed (euhedrische) of crystals in the form of a cube with characteristic striations and with a gold sheen. It is also called mad tinsel or gold (gold of the English fool's) because it sometimes for gold as was. However, the name cat gold is sometimes used incorrectly, this refers to yellow mica or resin. Because pyrite occurs largely can create the illusion of great wealth. However, pyrite is not worth very much (although it can be sold). It is found, together with other sulfur-containing minerals, but also with oxides, in quartz veins in sedimentary rocks in the carbon beds and as a replacement mineral in fossils. Pyrite is a disulfide with sulfur pairs (S2) 2, and Fe2 + ions in an octahedral surrounding t2g6 went into a low spin state. As a result of the fact that both ions have a closed configuration, it is a diamagnetic semiconductor. When the weathering of pyrite occur iron (hydr) oxides, which also releases sulfuric acid. This acid may then enter into reaction with other minerals, and thereby lead to the formation of, for example, gypsum, and aluniet jarosite. An important source of pyrite is the island of Elba. The name pyrite is very old, derived from the ancient Indo-European word pyr (fire, cf. Eg pyrotechnics fireworks art, or the English pyre (pyre) because one could create sparks by pyrite against flint or iron to catch on. Today The day we hear something different under flint (a form of SiO2). Other names that one of pyrite against can get his ferrosulfide, sulfur, iron and less common words ijzerblende and iron pyrites. Pyrite was used to be sold adulterated gold since the gold-like shine . However, the gloss changes when the glossiness flat tilts, with gold the gold shimmer is the same. Also, pyrite angular, with sharp edges and hard, while gold is round and soft.
