• ### What percent CaCO3 in limestone? Yahoo Answers

Sep 22, 2012· Dividing this mass by the mass of limestone we'll arrive at the percent composition. 0.38-g CO2 x (1 mol CO2 / 44.0-g CO2) x (1 mol CaCO3 / 1 mol CO2) x (100.1-g CaCO3 / 1 mol CaCo3) = 0.865-g CaCO3 % composition = 0.865-g / 1-g x 100% = 86.5% CaCO3

• ### 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 CaCO 3

• ### Techniques for Determining Limestone Composition and

Gypsum composition and purity are dependent upon limestone composition. When limestone possessing low available CaCO is fed to the system, limestone feed rates must increase to provide the same level of SO removal. In so doing, both limestone consumption and the level of impurities, including CaCO, within the slurry will increase.
