| description | The invention discloses a method for preparing clean coal, an ammonium fluorosilicate byproduct and a sodium metaaluminate product from coal gangue. The method comprises the following steps: microwave reaction, microwave acidification, ammoniation absorption and neutralization. Compared with domestic existing methods of acid dissolution, high-temperature calcinations and the like, the reaction time is greatly shortened, the reaction energy consumption is greatly reduced, a technological process is shortened, the whole processing process is low-carbon and environment-friendly, and environment-friendly efficient comprehensive development and utilization of the coal gangue is truly realized. |
