We all know that the main ingredient of limestone is calcium carbonate but sometimes it may also contain magnesium, iron or manganese affecting the whiteness and hardness of limestone. Nowadays, people like to use high-quality limestone to make powder by different crushing machines and ball mills.

In addition to acid neutralization capabilities, lime also serves as a source of calcium and magnesium. The magnesium content of aglime is important when a soil test indicates a need for magnesium. Magnesium requirements are met most economically by applying an aglime material that contains magnesium.

The magnesium content of limestone is especially important where soils are deficient in this essential plant nutrient. If a soil test indicates low magnesium, dolomitic limestone can be used to correct both the nutrient deficiency and pH. The value of limestone is in its ability to neutralize soil acidity. Limestone’s properties differ ...
Bavarder sur InternetActually, limestone usually contains a mixture of calcium carbonate and magnesium carbonate, which is called dolomitic limestone. For today, however, we will ignore that fact and assume our limestone contains only calcium carbonate.

Because each molecule of magnesium carbonate is lighter than calcium carbonate, limestones containing magnesium carbonate ( dolomite) can have a CCE greater than 100 percent. [12] Because the acids in soil are relatively weak, agricultural limestones must be ground to a small particle size to be effective.
