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.
Production of magnesium by vacuum carbothermic reduction of calcined dolomite R. Winand, M. van Gysel, A. Fontana, L. Segers and J.C.

Abstract. When a mixture of calcium oxide and silicon is heated to above 1000°C a liquid CaSi alloy is formed. When magnesium metal is produced by reacting calcined dolomite with silicon, the alloy still forms and is the effective reducing agent for magnesium oxide.
The IUPAC defines calcination as "heating to high temperatures in air or oxygen". However, calcination is also used to mean a thermal treatment process in the absence or limited supply of air or oxygen applied to ores and other solid materials to bring about a thermal calciner is a steel cylinder that rotates inside a heated furnace and performs indirect hightemperature ...
Calcined Dolomite or Flux Dolomite is the name given to the quicklime formed from calcining a natural dolomitic limestone that contains nearly an equal molar weight percentage of calcium oxide to magnesium oxide.
