Method for preparing pure calcite and ammonium sulfate from the waste gypsum

摘要

the present invention is immobilized in the crystal structure of carbon dioxide to the mineral carbonation reaction for the generation of calcite and sulfur by relates to a process for recycling to manufacture a high purity more than 95% of eyes , the present invention is to immobilize a safe mineral greenhouse gases is carbon dioxide and the reaction of carbon dioxide was also produced inside the pyeseokgo high purity calcite and sulfur as a result of high purity . ;
