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.

be used (915 kg/Mg (1830 lb/ton) lime produced for dolomitic limestone and 785 kg/Mg (1570 lb/ton) lime produced for calcitic limestone). These estimates are theoretical, based on the production of two moles of CO 2 for each mole of limestone produced. In some facilities a portion of the CO 2 generated is recovered for use in sugar refining.

Graymont's Lime operations are focused on the production of high-calcium and dolomitic lime, value-added lime-based products such as hydrated lime and precipitated calcium carbonate, as well as pulverized limestone and construction stone.

Dolomitic Lime. As the name suggests, dolomitic lime is manufactured by crushing dolomitic limestone down to very small pieces. As with agricultural lime, dolomitic lime works to increase the pH levels of acidic soil and return the earth to nearly neutral.

Dec 17, 2015· Dolomitic lime is derived from deposits of calcium carbonate combined with magnesium carbonate and contains much higher levels of magnesium. The key factors in deciding which of these types of lime should be applied to your soil is the soil pH and magnesium level. There is little difference between lime types in their respective ability to ...

Jul 04, 2019· Dolomitic limestone is a type of rock that includes up to 50% dolomite. Normal limestone is primarily made up of calcite and aragonite, but dolomite forms in the stone when the calcium ions in the calcite part are replaced by magnesium ions …

Jul 31, 2018· Hydrated Lime. Let's begin with hydrated. When limestone is burned to produce lime it releases CO2 gas. What remains is a highly alkali "quicklime." Quicklime alternatively known as "hot" lime is extremely reactive with water and can be dangerous to handle, transport or work with although it has its construction uses for experienced traditional masons and plasterers.

Lime is put to use in primary steelmaking and secondary refining processes. Electric Arc Furnace (EAF) and Basic Oxygen Furnaces (BOF, QBOP, KOBM): Quicklime (dolomitic and high calcium) is used by steelmakers as a flux agent to efficiently and effectively remove impurities such as phosphorus, silica and alumina from scrap melting in the EAF.

Dolomitic hydrated lime (pressure treated): this lime is produced from dolomitic quicklime under pressure, which results in hydrating almost all of the magnesium oxide as well as all of the calcium oxide, producing the following chemical composition: 40 to 42 percent calcium oxide, 29 to 30 percent magnesium oxide, and 25 to 27 percent water.
