Method for producing a high purity ammonium sulfate and calcite with gypsum

摘要

The present invention is related to methods for recycling is manufactured in high purity of more than 95 % of calcite and ammonium sulfate is produced by the carbonation reaction to be fixed in the crystal structure of the mineral carbon dioxide , waste gypsum a can be reacted with carbon dioxide, a greenhouse gas , it is possible to immobilize carbon dioxide secure minerals , it is intended to produce high purity calcite and high purity ammonium sulfate as a result thereof .
