|
|
|
| And companies are looking for other minerals that Sierra Leone has in abundance, such as gold, bauxite and rutile, a mineral that is used among other things to brighten the whiteness in paint, plastic and paper. |
|
| Major raw materials used for the production of titanium dioxide include ilmenite and rutile. |
|
| Sierra Leone has one of the world's largest deposits of rutile, a titanium ore used as paint pigment and welding rod coatings. |
|
| The reason that asterism is so rare is that it requires the gem to have inclusions of rutile needles, and for the needles to be aligned in such a way as to reflect light in a multi-ray pattern forming a star. |
|
| As the magma cools, REE elements eventually become concentrated in accessory phases such as zircon, rutile, ilmenite, titanite and monazite. |
|
| This sector includes mining of titanium-bearing minerals such as rutile, leucoxene, ilmenite, xenotime and monazite, and the industrial minerals zircon, kyanite and garnet. |
|
| Process for the purification of flue gas, wherein flue gas is contacted with a carbonaceous material, said carbonaceous material comprising the solid carbonaceous residue of synthetic rutile production from titaniferous ores. |
|
| Though it is one of poorest places on earth, it has deposits of diamonds, rutile and bauxite. Nobody believes that ECOWAS sanctions, whatever they turn out to be, will force the junta from power. |
|
| On 7 December 2004 the European Food Safety Authority stated that the use of rutile titanium dioxide in the platelet or amorphous forms would not pose any safety concerns. |
|
| Small-scale and industrial mining also pose considerable threats to the region's remaining tropical forests, as most of these are located on substrates rich in iron ore, diamonds, gold, rutile, and bauxite. |
|
| There is a technological need for the use of the platelet form of rutile titanium dioxide as a colour in foodstuffs and in film coatings for food supplement tablets. |
|
| Diamonds, gold, bauxite, rutile and iron ore are known to exist in large quantities, although geological studies have not yet mapped all the country's terrain, and may reveal additional mineral deposits. |
|
| Having been suspended in 1995, rutile and bauxite mining operations resumed in 2006 although rutile production was scaled down in 2008 following the collapse of one of the two dredges used to mine the mineral. |
|
| Reporters were provided the opportunity to board the FEDERAL KIVALINA, a Fednav Ltd. 'salty' loaded with 28,000 tons of synthetic rutile sand from Australia destined for Ashtabula, Ohio. |
|
| Some rose quartz contains microscopic rutile needles which produces an asterism in transmitted light. |
|
| Valuable mineral components often occurring with black sands are monazite, rutile, zircon, chromite, wolframite, and cassiterite. |
|
| It is also among the largest producers of titanium and bauxite, a major producer of gold and has one of the world's largest deposits of rutile. |
|
| Titanium dioxide has three crystalline forms including anatase, rutile and brookite. |
|
| It can be classified into anatase, rutile and brokite, of which only anatase and rutile are commercially important. |
|
| Titanium dioxide is mined from either the natural ores of ilmenite and leucoxene or rutile beach sand. |
|
|
|
| In case low concentration of rutile phase is added to anatase phase, photocatalytic properties of titania increase. |
|

|
| Haematite, tourmaline, zircon, rutile, ilmenite, sillimanite, geothite, and chlorite were also observed in Fe-Mn concretions. |
|
| Glass can also be coated with rutile to give pigments that iridesce with a blue, green, yellow or silvery sheen. |
|
| In addition, the clay minerals included common mica, occasional garnet group minerals, apatite, and rare titanite, ilmenite, zircon, rutile and iron oxides. |
|
| Titanium dioxide nanomaterials are created in various types of crystal structures, but currently only anatase and rutile nanoparticles are used for industrial purposes. |

|
| Rutile crystals, commonly associated with lazulite, pyrophyllite, and kyanite, are found at Horrsjoberg, Sweden. |
|
| Rutile is widespread in Canada as an accessory mineral in many varieties of crystalline rocks, although good specimens are not commonly encountered. |
|
| Rutile is a locally important constituent of hydrothermally altered rocks and is often seen as an accessory mineral in a variety of regional and contact-metamorphic settings. |
|
