Abstract. In the present work the solid solubilities of CaS and CaSQ, in burnt lime were investigated by equilibrating lime with COCO 2SO 2 mixtures at temperatures from 950 to 1300°C. Also, the equilibrium constants for the formation of CaS and CaSO 4 were determined. At high oxygen activities, corresponding to a CO 2 /CO ratio >100 in the gas, the sulfur dissolves in lime primarily as ...
Dolag (Dolomitic Quicklime) is a calcined or light burned dolomitic limestone. Firing in a rotary kiln drives off excess carbon dioxide and results in a chemically reactive calcium magnesium oxide product. It is used primarily as a metallurgical flux in basic slag practice steel melting by basic oxygen furnace or electric arc furnace.
There are 199 metallurgical grade alumina suppliers, mainly located in Asia. The top supplying countries or regions are China, Vietnam, and Slovenia, which supply 98%, 1%, and 1% of metallurgical grade alumina respectively. Metallurgical grade alumina products are most popular in Southeast Asia, Eastern Asia, and Mid East.
calcined lime/ burnt lime/ calcium oxide/ quick lime Calcium oxide or quick lime is widely used versatile chemical compound, made from excellent deposit of high calcium limestone. High calcium lime is used for acid neutralization, flue gas treatment, as flux in metallurgical industry, in sugar refining etc. Below are the different grades of ...
In the Dow process is magnesium hydroxide is precipitated from sea water by slurrying with calcined dolomite and then converting it to magnesium chloride by reacting it with hydrochloric acid. This product is dried to 1,5 moles of water and introduced directly into the cells.

AbstractThe silicothermic reduction of calcined dolomite in vacuum is the basis of production of magnesium metal. New data are reported on reaction kinetics under conditions where the reaction was shifted towards the products by entraining the magnesium vapour into hydrogen. The investigations were carried out in the temperature range 1070–1250°C, on single spherical pellets under closely ...

Gypsum is the crystalline chemical compound CaSO4·2H2O. A close chemical relation – and frequently occurring with Gypsum – is Anhydrite which is CaSO4. Gypsun has wide commercial use because relatively simple heat processing reduces it to Plaster of Paris. While Anhydrite can be converted to Gypsum and thence to Plaster of Paris, the procedure is not simple and is quite costly.
The Pidgeon process is a batch process in which finely powdered calcined dolomite and ferrosilicon are mixed, briquetted, and charged in retorts made of nickelchromesteel alloy.
