labradorite mineral information, data and localities.,a variety of anorthite a plagioclase feldspar with an albite : anorthite molar ratio ranging from 30 : 70 to 50 : 50. an intermediate member of the albite-anorthite series. labradorite can display an iridescent optical effect (or schiller) known as labradorescence. the cause of this optical phenomenon is lamellar structure caused by an exsolution process due to a miscibility gap..eramet agreement signed with tronox for the sale of, mineral sands mining operations in senegal (grande cote operations, 'gco') will remain controlled 1 by the group and will continue to supply ilmenite to .

what is ilmenite mineral? ilmenite, iron-black, heavy, metallic oxide mineral, composed of iron and titanium oxide (fetio3), that is used as the major source of titanium. it forms solid-solution series with geikielite and pyrophanite in which magnesium and manganese, respectively, replace iron in the crystal structure.
heavy mineral sands are a class of ore deposit which is an important source of zirconium, titanium, thorium, tungsten, rare-earth elements, the industrial minerals diamond, sapphire, garnet, and occasionally precious metals or gemstones.. heavy mineral sands are placer deposits formed most usually in beach environments by concentration due to the specific gravity of the mineral grains.
