How To Process Calcium Carbonate

Calcium carbonate has three crystalline polymorphs: calcite, aragonite, and vaterite. In the carbonation process, these crystals can be produced by changing various conditions such as concentration and temperature of lime milk, introduction rate of CO 2 gas, and whether or not chemicals are added.
