RCE A flue-gas desulfurization process in which the sulfur dioxide is absorbed in aqueous magnesium hydroxide. The product is reacted with calcium chloride to produce gypsum, and the magnesium hydroxide is regenerated by treatment with dolomite. Developed by Refractories Consulting Engineering, Germany, and piloted in Austria. 

In 1792 Anton Rupprecht prepared impure magnesium (contaminated with iron) by reduction of magnesium oxide with carbon and called the metal austrium in honor of Austria (68). 

In 2008, the largest producer of magnesium metal was reported to be China. Other large producers included Brazil, Israel, Kazakhstan, and Russia. The largest producers of magnesite were China, Turkey, North Korea, Russia, and Austria. The amounts of magnesium metal and magnesite produced in the United States were not reported in order to protect trade secrets. 

Deposition rates of locally generated dust, which is rich in calcium and magnesium, are high in the Limestone Alps of Austria. Alkaline dust particles have the size range of 1 to 20 xm. Dusts containing lime react as alkaline. 

It is formed as a replacement mineral of magnesium-rich rocks when carbon dioxide is available. Magnesite is mined both as an ore for magnesium and as a source of magnesium carbonate. It occurs in Austria, USA, Greece, Norway, India, Australia, and South Africa. 

Hydrotalcite is a natural mineral with a white color and pearl-like luster. It is mined in small quantities in Norway and the Ural area of Russia. Other mines of hydrotalcite are located in Austria, Canada, Czech Republic, Germany, Sweden, South Africa, and United States [7]. Natural hydrotalcite is a hydrated magnesium-, aluminum- and... 

TALC. 3Mg0-4Si02-H20. Talc is a hydrous magnesium silicate, with the composition 63.4% SiOj, 31.9% MgO and 4.7% HjO when found in pure form. It is an extremely soft mineral with a Mohs hardness of 1, has a platy structure and it is naturally hydro-phobic. Talc occurs as a relatively pure massive mineral in Montana, Australia and China. Elsewhere it occurs in conjunction with magnesite (Vermont, Quebec, Ontario and Finland), with tremoUte and serpentine in New York and with chlorite in France and Austria. In many ceramic applications, the presence of non-talc minerals such as chlorite and tremolite are beneficial. 

I have no specific information concerning the addition of magnesium oxide. As far as I am aware, industrial salt containing iodide supplementation is only used in Austria, in the bakeries in The Netherlands, and in Switzerland. For Austria and Switzerland, this corresponds approximately to 65-70 % of the industrial salt. The 30 % of Swiss industries which do not use iodinated salt, do so mainly for reasons of export of food products into...
