What is Calcium Carbonate? - Industrial Minerals ...

As limestone, calcium carbonate is a biogenic rock, and is more compacted than chalk. As marble, calcium carbonate is a coarse-crystalline, metamorphic rock, which is formed when chalk or limestone is recrystallised under conditions of high temperature and pressure. Large deposits of marble are found in North America and in Europe; e.g., in ...

Carbonates Other Rocks

Carbonate Rocks. The carbonate rocks make up 10 to 15% of sedimentary rocks. They largely consist of two types of rocks. Limestones which are composed mostly of calcite (CaCO 3) or high Mg calcite [(Ca,Mg)CO 3], and . Dolostones which are composed mostly of dolomite [CaMg(CO 3) 2]. Because carbonate minerals in general are soluble in slightly acidic waters, they often have high porosity and ...

Mineral Fertilizers - For Boosting Soil Fertility

Calcium carbonate – also known as high-calcium lime or calcitic lime – is the main calcium fertilizer used to increase soil calcium levels. It’s not to be confused with hydrated lime or quick lime, which can burn crops as well as your skin. Calcitic lime contains approximately 30%-40% calcium and often around 2-4% magnesium.
