Chemical Limestone Graymont

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).

Dolomitic Quicklime Graymont

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. Limestone can also contain magnesium carbonate (magnesite:MgCO 3) and CaCO 3 separately. The proportion of MgCO 3 can be used to classify the different types of magnesian limestone as presented in Table 1 [4]. The terms ‘‘magnesian limestone’’ and ‘‘dolomite’’ are used for any calcareous rock contain-

Agricultural Lime vs. Dolomite Lime Braen 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.

Dolomite (rock) Wikipedia

Sep 27, 2004· Dolomite (also known as dolomite rock, dolostone or dolomitic rock) is a sedimentary carbonate rock that contains a high percentage of the mineral dolomite, CaMg(CO 3) 2.In old USGS publications, it was referred to as magnesian limestone, a term now reserved for magnesium-deficient dolomites or magnesium-rich limestones.Dolomite has a stoichiometric ratio of nearly equal amounts

Understanding Plant Nutrition: Limestone, Calcium And

Jun 10, 2008· Limestone Nutrient Content There are four types of carbonate-based limestone that are available. Calcite is pure calcium carbonate (CaCO 3, 40 percent Ca).Calcitic lime is composed of mostly CaCO 3 (> 30 percent Ca) with some MgCO 3 (<5 percent Mg). Dolomitic lime contains less CaCO 3 (<30 percent Ca) and more MgCO 3 (>5 percent) than calcitic lime. Finally, dolomite also contains
