Magnesium Carbonate Limestone

Dolomite (rock) Wikipedia

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 of magnesium

Magnesium Carbonate an overview ScienceDirect Topics

Limestone, a naturally occurring sedimentary rock is composed of high levels of calcium, or magnesium carbonate, or dolomite, 5 and other minerals. After removal from quarries and mines, the stone is crushed, which may be followed by secondary or tertiary crushing and screening into particles ranging in size from several inches to dust.

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 CaCO 3 and
