| Abstract: | Magnesium can be extracted from calcined ascharite mineral by aluminothermic method under vacuum condition.In this paper effects of briquetting pressure of ascharite mineral and calcium carbonate,and calcination temperature and calcination time on ignition loss and on magnesium reduction rate are studied.It is showed that higher reduction rate of magnesium can be achieved through briquetting at 45MPa~60MPa,calcinations at 950℃~1000℃ for 0.5h. |

| Keywords: | ascharite mineral magnesium calcinations reduction rates |
