Limestone is a source of calcium carbonate and is heated to convert the calcium carbonate into calcium oxide. This process is generally carried out in large rotary kilns or vertical shaft kilns where high temperature is required. Quicklime is produced in the calcination process, which can be crushed depending on it's use.

Dolostone (Limestone)

The principal mineral of limestone is calcite (CaCO3), a form of calcium carbonate. Dolostone is quite similar to limestone, but is composed mostly of the mineral dolomite (CaMg(CO3)2). Both are sedimentary rocks that occur as thin to massive beds of fine- to coarse-grained rock.


Many minerals contain calcium. Calcium minerals are very common and can be mined anywhere. It is chiefly obtained from limestone, dolomite and gypsum. Common calcium-bearing minerals include anhydrite (calcium sulfate), gypsum (hydrated calcium sulfate), and aragonite or calcite (calcium carbonate).
