Limestone (calcium carbonate - CaCO 3) is present in large quantities in natural rock around the world.; Lime (calcium oxide - CaO) is an alkali and the result of the chemical transformation of limestone by heating it above 900°C, which requires energy (3.2 GJ/tCaO). Given its rapid reaction with water, calcium oxide, also called burnt lime, is often referred to as quick lime.

If the proper chemical control is maintained on lime feed, the calcium hardness may be reduced to 35-50 ppm. Magnesium reduction is a function of the amount of hydroxyl (OH-) alkalinity excess maintained. Figures 7-1 and 7-2 show these relationships.. Noncarbonate or permanent calcium hardness, if present, is not affected by treatment with lime alone.

Why is Dolomitic Limestone better | Pattison Company

 · Dolomitic Limestone has been around for a very long time and has gone through many name changes over the years. Dolomitic Limestone was originally known as "Magnesium Limestone," as it contains high levels of magnesium instead of just calcium. So just about anyone who can use magnesium should be interested in it.


Hypomagnesemia is serum magnesium concentration < 1.8 mg/dL (< 0.70 mmol/L). Causes include inadequate magnesium intake and absorption or increased excretion due to hypercalcemia or drugs such as furosemide. Clinical features are often due to accompanying hypokalemia and hypocalcemia and include lethargy, tremor, tetany, seizures, and arrhythmias.

Effect on Trace Elements. The higher the calcium level climbs from the use of calcium carbonate limestone, or gypsum, or from the calcium make-up of dolomite lime, or any other significant calcium source, the more chance the trace elements, plus potassium and magnesium, have of being tied up in the soil – to the point that the crops can no longer take them up.
