Chemical Properties Of Limestone

calcination of limestone – ispatguru,limestone can be classified according to their chemical composition, texture and geological formation. typically, limestone contains more than 90 % caco3 (calcium carbonate) and a few % mgco3 (magnesium carbonate). dolomite is a double carbonate containing 54.characteristic study of physical and chemical properties,analysis on minerals composition detected that limestone that has been used in this study contain major portion of caco 3 (97.91%) and can be classified as high purity limestone. based on the ftir analysis of the raw limestone, it shows that the presence of hydroxyl group with o–h stretching is a favourable group of fe and mn adsorption..
