Calcite Mineral | Uses and Properties

Calcite has numerous uses as a neutralizer of acids. For hundreds of years, limestones and marbles have been crushed and spread on fields as an acid-neutralizing soil treatment. They are also heated to produce lime that has a much faster reaction rate in the soil. Calcite is used as an acid neutralizer in the chemical industry.
