High-calcium Limestone Graymont mines some of the best limestone deposits available. As a result, we can produce a chemical-grade limestone that satisfies a wide range of industrial and agricultural specifications. Applications of this product include the supply of high-calcium sized stone as a lime kiln feedstock, in order to meet the specific raw-material needs of the various PCC markets and ...
Dolomitic limestone contains about 35% to 45% magnesium carbonate (MgCO 3); the remainder is primarily CaCO 3, again with 1%—3% impurities. The balance of calcium and magnesium content effects the glassmaking process in a number of ways.
Techniques for Determining Limestone Composition and Reactivity
Dolomitic limestone, or dolomite (MgCO 3 +CaCO 3), is also a commonly used source. Dolomite usually costs a little more than calcitic limestone and changes the soil pH more slowly, but it has the advantage of containing Mg as well as Ca. Together, calcitic limestone and dolomitic limestone account for more than 90 percent of the lime used in ...
There are three distinct types of limestone, defined by their magnesium carbonate (MgCO 3) concentrations.These types are Dolomitic (35 to 46% MgCO 3), Magnesian (5 to 35% MgCO 3) and High calcium (less than 5% MgCO 3).
The convention within industry has been to assume that all of the MgCO 3 in limestone is dolomitic, with an equimolar molar ratio of MgCO 3 and CaCO 3. Actually, ...

DOLOMITE AND LIMESTONE Executive Summary MgCO Limestone is defined as a calcareous material or rock with a limestone content (CaCO 3) of at least 70%. Lime, limestone and dolomite products are used in four principal industries in South Africa: Cement manufacturing, metallurgy (steel refining), manufacturing and agriculture (fertilizers, fungicides,
but commercially, lime is understood to mean the product of complete calcinations of limestone, which may vary from pure calcium carbonate CaO 3.MgCO 3, thus commercial lime many contain as high as 45% of magnesium oxides MgO as well as such impurities as silica, iron oxide and aluminium. Farmers need no introduction to RDF Agricultural Lime.
The convention within industry has been to assume that all of the MgCO in limestone is dolomitic, with an equimolar molar ratio of MgCO and CaCO. Actually, the molar ratio of these species can vary considerably from crystal to crystal, and the reactivity of each crystal varies in relation to the fraction of MgCO in the crystal. ...

are calcite and dolomite. Limestone often contains magnesium carbonate, either as dolomite CaMg (CO 3) 2 or magnesite (MgCO 3) mixed with calcite. It is then termed 'dolomitic' or 'magnesian' limestone. Such limestone contains 10 to 40% MgCO 3. Limestones altered by dynamic or contact metamorphism become coarsely crystalline and are referred to ...
85% (284 ratings) Problem Details. A sample of dolomite limestone containing only CaCO 3 and MgCO 3 was analyzed. When a .3028 gram sample of this limestone was decomposed by heating, .082 L of CO 2 at 754 mmHg and 22 degrees Celsius were evolved. The …
Dolomitic quicklime is lime made from high-quality deposits of dolomitic limestone; limestone containing 40% to 44% magnesium carbonate (MgCO 3 ). Dolomitic quicklime (MgO·CaO) commonly known as dolime is a widely used chemical compound. It is a white, caustic and alkaline crystalline solid. As a commercial product, dolomitic quicklime often ...

Dolomite is a double carbonate of calium and magnesium, CaCO 3, MgCO 3. It is of sedimentary origin and is supposed to have been formed due to chemical action of sea-water containing high percentage of magnesia, on limestone. Theoretically, dolomite contains: CaCO 3 - 54.35%. MgCO 3 - 45.65%. In other words, it contains: CaO - 30.4%. MgO - 21.7%.
