RARE ILMENITE QUARTZ SPECIMEN 1
In stock
A Rare Ilmenite Quartz Specimen 1 for sale. A solid Ilmenite on Quartz Matrix with another silvery associated mineral – Bismithinite is one of the minerals associated with Ilmenite. Good portions of the metal on this specimen are crystalised. Fossicked over 20 years ago and the location is now permanently closed. It is from a location with some radioactive ore, the fossicker who found this treasure advises this rock is not radioactive. This is a rare metal mineral specimen for the avid metal mineral collector. Reminds me of weeing a specimen labeled Titanomagnetite in the Museum of Australia – interesting rocks.
Location:
Arkaroola Bore, Arkaroola, South Australia, Australia.
Dimensions:
9.7cm x 8cm x 5.2cm, 600g.

Ilmenite is an economically important and interesting mineral. Named for its place of discovery at Ilmen Lake in the Ilmen Mountains, Miask, southern Ural Mountains of Russia. Ilmenite forms as a primary mineral in mafic igneous rocks and is concentrated into layers by a process called Magmatic Segregation. It crystallizes out of a magma early before most of the other minerals. Heavier crystals of Ilmenite fall to the bottom of the magma chamber and collect in layers. These layers form a rich ore body for Titanium miners. Ilmenite also occurs in pegmatites and some metamorphic rocks, as well as in the sedimentary rocks that are formed from weathering and erosion.

History
Since its discovery, the mineral Ilmenite has grown greatly in its importance. It is now the most important ore of titanium. Titanium was at one time a metal that had little use and basically no one knew what to do with it. Even as late as 1946 when the metal was finally shown to be capable of being produced commercially, it was considered a laboratory curiosity. Since that time, titanium has been shown to be a strong aluminum-like metal, light weight, non corrosive, able to withstand temperature extremes and it has good strength. Titanium alloys have found many applications in high tech airplanes, missiles, space vehicles and even in surgical implants.
Titanium dioxide TiO2 is a white pigment that is used more and more in paints. The largest percentage, up to 95% of world wide use for titanium is for the production of white pigment. Titanium Dioxide also is used for coating Silicon Dioxide to form Solar Panels and Titanium Aura Quartz specimens.
