Improved extraction of alumina from coal gangue by
01.11.2016These results indicated that grinding effectively activated coal gangue and improved the extraction of Al 2 O 3. Calcination further improved the extraction of Al 2 O 3: after calcination at 750 C the alumina dissolution reached 70% after only 2 h grinding. The alumina dissolution increased with increasing grinding time, reaching 95% after 20 h.
