Preparation of strontium carbonate from celestite: Mineral ...

2013-7-18  A novel method for the preparation of strontium carbonate from celestite ore has been investigated. The ore is reduced by brown coal at a temperature of 1000°C for a period of 3 h. The reduced product is leached with water at a liquid : solid ratio of 3 : 1 at 90°C and the slurry is then leached with hydrochloric acid at a solid :
