Calcium carbonate Essential Chemical Industry

Calcium carbonate. For a particular use, an appropriate choice is made from the four: limestone, quicklime, slaked lime or milk of lime. In many uses, lime reacts more quickly than limestone but is more expensive, because a high temperature is required to produce it from limestone.
