Titanium dioxide pigment (and titanium metal)
Time:2009-1-5 14:58:15 | Publish:admin | Hits:
Titanium dioxide (titanium dioxide) is a white powder with a high degree of transparency, brilliant white, good coverage and the ability to change color against. These characteristics make a valuable and opacifier pigment widely used in paints, plastics, ink and paper.
The pigment is processed and manufactured to contain naturally occurring rutile or titanium mineral ilmenite. Rutile is a kind of impurity in the form of titanium dioxide and ilmenite contains titanium and iron oxide combined with the compound. Although common in parts of the world, they are most likely to be used, Australia, the United States, India and South Africa.
In Australia almost all of titanium dioxide from ilmenite, as it occurs naturally in high concentrations and can form, ready to allow extraction of rutile. These favorable factors ilmenite competitive producer of the raw materials Australia exports reflected in the high activity.
Energy use of low-cost regions slagging.
Australia supplies about 40 percent of the world's ilmenite, about 25 percent of rutile. On the contrary, it has the advantages of titanium minerals, Australia supplies about three per cent share of world titanium dioxide production of about 40,000 tons. This huge imbalance means that the opportunity to further increase the value.
In 1995, Western Australia produced 1,600,000 tons of titanium dioxide is about the value of 350,000,000 U.S. dollars.
To June 1998, Australia is expected to export 11,000,000,000 for the titanium minerals, of which two-thirds of exports to Europe and North America.
Science and Technology
Production of titanium dioxide pigments, whether chlorine or sulfuric acid process (Australia only the use of chlorine in the process). The technology is a process closely held Chlorination Ticor Keermaiji is authorized under the brand also sells its pigments.
Sulfuric acid process
Kraft is the first commercial-scale process technology for conversion of ilmenite for titanium dioxide. A large amount of waste iron sulfate production and a poor-quality products, most of the applications, the process of a number of sulfuric acid plant under construction. In 1996, Tioxide, a sulfuric acid plant on the basis of Bernie, Tasmania, 1473, approximately 40 years of operating the use of ilmenite shipments from Western Australia and sulfuric acid from the local metal smelting operations in the Tasmania. The plant produced a large number of scrap iron sulfate. Sulfuric acid in the production process as a form of pigment known as the sharp, which is better than chlorine-derived pigments can be used for paper, ink and ceramics.
Bullets in the place of cheap electricity, such as South Africa (coal) and Norway (hydropower), which can be slagged ilmenite and rutile production of iron. In Australia, Becher in the process of iron oxide waste generated This is a re-adjustment of the mine site.
Chlorination process
The new chlorination process to avoid the problem of waste iron sulfate, and on a larger scale, less expensive operation. This process needs to be dealt with ilmenite in the form of rutile (that is, the removal of iron component of the oil production of titanium dioxide [synthetic rutile]) and thorough process in Western Australia. Under normal circumstances, 1.06 tons of man-made rutile is a requirement for each ton of pigment.
Chlorine process, because now dedicated in Australia, the response of man-made chlorine and rutile form of titanium tetrachloride and then oxidized to stay volatile ferric chloride and other impurities, chlorine, mostly re-cycling. Chlorine consumption, therefore, the amount of iron oxide (alumina) to stay in man-made rutile is usually 4 percentage points. Ferric chloride is harmful to the environment it is a lime into the iron oxide and calcium chloride discharge into the sea.
About one tonne of chlorine are required to produce 5-6 tons of titanium dioxide (as the iron content of rutile for the consumption of chlorine and ferric chloride about one-third of the end of the chlorine as hydrogen chloride). Tiwest now supply hydrochloric acid to libraries Kyrgyzstan converted to ammonium chloride (used in the production of synthetic rutile).
The use of rutile (ilmenite, not iron), chlorination plant to avoid the production of a greater amount of ferric chloride has been closed for disposal (for example, by the deep well used to dispose of DuPont of the United States).
After the removal of salt, vanadium, and further fractionation, pure titanium tetrachloride with the reaction of oxygen, resulting in a high temperature titanium dioxide. In the titanium dioxide coating and the ground is a different level. The liberation of chlorine recovery. In other words, the consumption of chlorine larely ferric chloride is converted to hydrogen oxide lime treatment. The resulting calcium chloride and iron oxide can be safely disposed of.
Around the world to have a significant swing in the use of chlorine and some new sulfuric acid plant is being established. Chlorination process products with a more stringent control, reduce labor-intensive, and environmental safety. There are about 60 percent of about 4,000,000 tons of the pigment production worldwide production of chlorine produced by the process. While declining to respond to worry about the environment unacceptable waste, many of the sulfuric acid plant to postpone the introduction of innovative technologies close. This status will help lower the price of synthetic rutile.
Chlorination plant needs a high-grade rutile. In the lower grades of ilmenite (titanium 52-57 percent) is Western Australia's exports of titanium minerals producer oveseas sulfuric acid-based plants and electric arc furnace. Producers of low-grade ilmenite can not be converted into synthetic rutile in the current economic status in the world of low-cost slagged ilmenite (nucleide zero).
Nucleide the problem is that monazite ore containing six per cent of the radioactive element usually contains thorium (and some of the uranium. In 1990, about 130,000 tons of production monazite, but dropped to zero due to competition nucleide free sources, such as China. Interested in dealing with monazite in the Rhone-Poulenc pinjarra.
Industry
About 40 percent of the national production of ilmenite (about 80 U.S. dollars per ton) is converted to synthetic rutile (470 U.S. dollars per ton) and 40 percent, only about 30 percent into paint (worth about 2 000 U.S. dollars per ton). In other words, the pigment production may be increased by 8 times!
There are two manufacturers of titanium dioxide pigment in Western Australia, the International Millennium Chemicals (military, the former Chemical Co., Ltd. Supply Chain Management) in Kemerton, Western Australia andTiwest joint venture in Kwinana, Western Australia.
