Abstract:
Provided is a recycling method for producing calcite and ammonium sulfate having a high purity of at least 95% and generated by means of a carbonation reaction for fixing carbon dioxide inside the crystal structure of a mineral, and in which waste gypsum is reacted with carbon dioxide, which is a greenhouse gas, such that the carbon dioxide is fixed as a stable mineral, and high-purity calcite and ammonium sulfate are produced as resultant products.
